KERATIN SALON/DIRECT Keratin Smoothing Treatment (KSD) is a transformational, long lasting and safe treatment that brings hair to its ideal, most beautiful condition without damaging or dangerous chemicals like formaldehyde, which can be found in other straightening or smoothing products.

KSD will reduce frizz and deliver straighter, smoother, stronger, healthier looking, more manageable, and exquisitely beautiful hair and will last for months.

Regular salon goers who have used KSD report great results with respect to reducing frizz and curl that lasts for months, but there is nothing like having a professional stylist do your hair in your favorite salon, but this may be the next best thing for managing unruly hair until the salon experience returns to what it was before COVID.

KSD is the perfect treatment to eliminate frizz and provide smoother, straighter and more manageable hair that will last for months.

KSD is a transformational product which will reduce curl and wave.  Like any professional smoothing system, the amount of curl or wave that is reduced depends on the hair type and texture. If you do NOT want to reduce any curl or waves, KSD is not the right treatment for you.  If you are not sure, do the treatment on a small section at the nape of your neck to test the results.  As with any professional hair product, KSD is not for everyone.  Hair that is extremely dry, damaged, heavily bleached, very delicate or has extensive split ends should consider appropriate moisturizing treatments and hair trims to bring the hair back to health before using KSD or any other professional service.

You can do the KSD Keratin Smoothing Treatment as soon as you wish.  However, many of these traditional keratin smoothing treatments (Brazilians) may have damaged your hair. If you are currently experiencing breakage or feel your hair is extremely dry, damaged, heavily bleached, very delicate or has extensive split ends, you should consider appropriate moisturizing treatments and hair trims to bring the hair back to health before using KSD or any other professional treatment.

Yes, as long as you have enough.

Yes. Stylists who used KSD or provided it for their clients during the period their salons were closed reported excellent results and that they want to continue to offer KSD as an option for their clients who are not yet comfortable spending hours in a salon for a traditional keratin smoothing treatment. Stylists and clients have both reported that they prefer it to the harsh chemicals of many salon smoothing treatments.

KSD will last for months if you follow the directions for your hair type and texture. Like formaldehyde-based keratin smoothing treatments (sometimes referred to as“Brazilians”) the amount of time KSD will last varies by hair type, hair texture, and maintenance routine. 

No. The results of KSD are much more like a salon keratin smoothing treatment and is safe to do at home without formaldehyde and the associated risks. It is not a lye relaxer or no-lye relaxer and it is not a Japanese straightener – both of which SHOULD be done by a licensed stylist as they require close attention - and will not deliver identical results. Japanese Straighteners deliver pin straight hair and use Ammonium Thioglycolate as the active ingredient (pH of between 9 and 9.6 which is Alkaline). Many relaxers use sodium hydroxide (lye) as the active ingredient (pH of between 12 and 14 which is even more Alkaline) to deliver pin straight hair.  After a Japanese Straightener or Lye or No-Lye Relaxer, many find it difficult to curl hair or get volume in the hair. KSD works differently.  It has a pH similar to a lemon and allows many styling options after the treatment including but not limited to curling/bending hair and volume blow dries.

No. KSD gives you the hair you want without harsh chemicals like lye (sodium hydroxide), no-lye (guanidine carbonate) or ammonium thioglycolate that can damage your skin or your scalp. It contains no formaldehyde or aldehydes of any type.  It is safe, easy and you can do it yourself at home.

KERATIN SALON/DIRECT’s proprietary formulation is comprised of a combination of safe and effective ingredients that have been used for many years in hair care and in the food industry, including keratin and a proprietary blend of nutrients, including conditioners, vitamins, and botanicals. KSD penetrates through the cuticle of the hair and gently modifies the bonds, while it is delivering its nutrients deeply into the hair strand delivering soft, smooth, manageable, lustrous hair. During the flat iron process, the ingredients are locked into place.

It is our proprietary blend that includes keratin, amino acids, wheat germ oil, jojoba seed oil, Vitamins C, E, and B6.

Keratin is the primary protein in hair.

We are a team that has developed products that you know and love and find in the finest salons in the world from Beverly Hills to New York, from London to Paris. We make products for the top salon brands.  We developed KSD to allow salon clients to have the beautiful manageable hair that they love, while the salons were shut down.


No. Follow the instructions.  They are simple and require no special tools.

Yes. There are no strong chemicals, but gloves are recommended and are included. 

Yes. One of the top testing labs in the United States performed the HPLC test on KSD and found no detectable formaldehyde.

Like with any professional treatment, it is not recommended.  The treatment could temporarily tarnish jewelry.

Yes. We developed KSD so you can easily use it in your home without your stylist with no need for special tools or ventilation.

No comparison. If you have used some of these treatments, you know the strong odor and the results. Most carbocysteine products wash out very quickly, sometimes in just weeks. KSD delivers reduced frizz, straighter, smoother, stronger, healthier looking, more manageable, and exquisitely beautiful hair and will last for months.

The GOOD NEWS is that the odor will go away and is generally only noticed when the hair is wet. Depending on one’s hair type and texture, some people experience a lingering odor, but it will go away as you continue to wash your hair.  This could be a result of NOT having rinsed enough when you did the treatment before you did the blow dry.  If you did not get your hair 100% dry before you flat ironed when you did the treatment, that could also have caused this to occur.

No. KSD is gently modifying the bonds with a pH similar to a lemon — which is gentle.

No. KSD is not a relaxer and it is not a reverse perm. It is a new and different technology. KSD gently modifies and restructures the disulfide bonds in the hair to soften the overall shape of the curl.  Lye relaxers use sodium hydroxide with a pH of 12-14.  There are “no-lye”relaxers which use guanidine carbonate, with a pH of 9-11.  Japanese straighteners use ammonium thioglycolate with a pH of 9 to 9.6. These products are strongly alkaline, and a neutralizer must be used.  If the process is not timed correctly, these alkaline products can quickly destroy the hair. KSD is not alkaline at all. It does not contain sodium hydroxide, guanidine carbonate or ammonium thioglycolate. 

KERATIN SALON/DIRECT —  Keratin Smoothing Treatment is different. It has been developed as a salon smoothing system that you can do at home because of the Covid-19 crisis. We are a next-generation smoothing system that uses the latest advances in science, along with only the finest ingredients, to create a product that delivers the results salon clients demand from a keratin smoothing treatment, safely and effectively. And, because KSD works from the inside out in modifying the overall shape of the curl, our results last for months.

Yes. KSD uses a revolutionary pH system with similar acidity to a lemon to open the cuticle to allow the infusion of a proprietary blend of keratin, botanical extracts, and vitamins to enter through the cuticle to the cortex.

No. There may be a slight odor during the treatment but that is normal. It gives off no fumes. In some cases, not all, there may be a slight smell in the hair after the treatment, but this disappears after a few washes. To minimize this, be sure that the hair is rinsed as per the instructions and thoroughly dried before flat ironing. Even though this will disappear after the first few washes, it can be minimized or eliminated if the hair is thoroughly blown dry and not air dried.

Although KSD delivers remarkably similar results to these treatments, it does not make the hair so flat that you cannot put a bend in the hair with a flat iron or curling iron.

Unlike most smoothing treatments, with KSD the hair can be washed immediately and there are no restrictions to exercising, wearing ponytails or clips. Any styling products may be used immediately. 

Although KSD contains no formaldehyde or other carcinogens or dangerous chemicals, it is the Company’s policy not to recommend any products to pregnant women or children. If you are pregnant and elect to use the product or if you elect to use it on children, check with your physician first.


As with any professional hair product, KSD is not for everyone.  Like any keratin smoothing treatment, the amount of curl or wave that is reduced depends on the hair type and texture. If you do NOT want to reduce any curl or waves, KSD is not the right treatment for you.  If you are not sure, do the treatment on a small section at the nape of your neck to test the results.  Hair that is extremely dry, damaged, heavily bleached, very delicate or has extensive split ends should consider appropriate moisturizing treatments and hair trims to bring the hair back to health before using KSD or any other professional treatment.

Yes, KSD works great on African American and/or resistant hair. KSD will reduce frizz and deliver straighter, smoother, stronger, healthier looking, more manageable, and exquisitely beautiful hair and will last for months. It is not a lye or no-lye relaxer and it is not a Japanese straightener and will not deliver identical results.

It is important that all the hair is completely coated, especially the ends which tend to be the driest and most porous.

No. Follow the instructions to make sure you get the best results. Unnecessarily increasing heat can damage hair. Excessive heat may also activate unwanted lifting of color.

Yes, if they are human hair. Avoid the bond while flat ironing.

There is nothing in the product itself to turn the hair yellow or orange, but blonde or white hair - either bleached or unbleached - has been known to turn yellow or orange for a variety of reasons. This could occur during the treatment and it may be outside your control. Causes could include type of color or treatments that are already in your hair, type of water, medication—even an aspirin can affect hair color!


Another thing that can cause a problem is a flat iron that was too hot for delicate white or blonde hair. That is why the directions recommend starting at the lowest temperature on your flat iron.  Remember the goal is to get the hair silky.  It is simply a matter of adjusting the temperature only to the point where the hair gets easily silky. It is not necessary to do a lot of passes, generally no more than 3. If you elect to do the treatment again and if you should see the hair getting yellow or orange, STOP and turn the temperature down. DO NOT over flat iron the hair. Silky is the key word. Once it is silky there is no reason to continue to flat iron. If you should experience this issue, stylists with whom we discussed this question suggest that blue/violet based shampoo can reduce/eliminate discoloration as can a toner.


Color or Toner may be applied immediately after the treatment and can be applied on the flat ironed hair if your hair feels light and silky.  Should your hair feel heavy or like it has extra residue after the treatment, simply wash your hair before you color it or apply a toner. 

It is important to follow the directions, but if you are not exactly right on the timing, it will still work fine. A few minutes longer will not damage the hair but try to stick with the recommendations for the best results.

Because the pH is about the same as lemon juice you might notice some tingling if you have sensitive skin or have abrasions on your scalp. This is normal and will disappear completely once you rinse the hair. 

As with all smoothing treatments, there is a potential to lift color. Whether or not any color is lifted and how much color is lifted is a function of the hair type and condition as well as the type of color and the temperature of the blow dryer and/or flat iron. If your hair has pink, blue, green, yellow or any other bright unnatural colors, there may be a greater tendency for lift. 

Some folks choose to color before & some color after.  If you color AFTER which is preferred, you will not have color lift. If you color after treatment it can be done the same day or any time after. If you color BEFORE the treatment, KSD’s SMOOTH formula, like all smoothing treatments, may lift some color & make highlights appear brighter. Some stylists who color BEFORE report that they deepen the color by a few levels to account for some lift that may occur during the treatment. Whether or not any color is lifted & how much color is lifted is a function of the hair type, texture & condition as well as the type of color. It helps to reduce the heat on your blow dryer & flat iron during the treatment as excessive heat can also lift color.

Yes. If you prefer to simply air dry your hair at any time after the treatment, be sure to use the included addictive KSD Styling Crème to define your curl and wave.  For best results, use the KSD Moisturizing Shampoo & Conditioner.

No. Many people prefer to air dry or just use a blow dryer. The only time to use a flat iron thereafter is when you want to.

If you are unsure about using this or any professional treatment, a strand test is always a good way to see if you will be happy with the results.  If you elect to do a strand test and if you are not completely happy with the results, we will send you a full refund, no questions asked.

We manufacture and ship from Florida.  Our manufacturing facility has been making products for some of the finest salon brands in the world for almost two decades.

The fastest and easiest way to apply KSD is to squeeze a small amount at a time of KSD into your hands, rub your hands together and apply it to your DAMP or DRY hair with your fingers in the same way you would with shampoo and MASSAGE it into your roots and hair (see directions). If you prefer to use an applicator brush, that is fine, but it will take you longer as you would need to first section the hair and put the treatment into a glass or plastic bowl instead of your hands.

Yes. It is even faster to apply to damp hair, but there may be slightly less longevity than if applied to dry hair. 

No, but you can if you want to, especially if you have oily, virgin, or uncolored gray or a lot of product build up in the hair. Otherwise, it is all right to use your regular shampoo and conditioner.

You may use any shampoo and conditioner. The type of shampoo and conditioner used will not affect the longevity of the treatment.

Yes, you will have the same faster drying experience with KSD as with past keratin treatments. You can use whatever shampoo and conditioner you wish. The type of shampoo & conditioner you use will not affect the longevity of the treatment. 

Our products are available now, for the first time, direct to the end user. We know that we will get rave reviews and we will post them, of course. Our team’s business model has always been to sell our products through distributors to salons and stylists. We make the products that you see in fine salons all over the world. Up until the Coronavirus made it difficult for clients to get to salons, we did not sell directly to consumers.  

Professional hairstylists and salons are quite important to us and we respect the challenges they are facing. Many folks just cannot get to the salon or find the current salon experience less pleasant than before COVID, so we are offering KSD directly to the consumer. It is a service that can be done safely at home. KSD does not require special training or ventilation.  Anyone can do it and achieve great results. 

Some of the top stylists in the country have used it on their clients with great results. The group of scientists and hair professionals who developed KSD have been formulating smoothing treatments for many years for sale to stylists, salons, and spas.  Products we developed are in more than 17,000 salons. We originally developed KSD, prior to the Coronavirus, for sale to premium salons. When the virus took hold and our salon customers were closed, we decided to make KSD available directly to the consumer.


Yes. If you choose to go to the salon to have a traditional keratin treatment, that would be fine although you may not find it necessary.

That is what most people do.  However, if you are loving your hair as it is except for a certain area, like your bangs, you can treat just that specific area. 

No, that will not work and will not give you good results. A flat iron is required to seal the botanicals, nutrients, and proteins into the hair. For best results, use a flat iron with a temperature control that allows you to get to the temperature you need for your hair type and texture as per the Directions for Use.

You can swim immediately after the KSD treatment, and this would not affect the effectiveness. Both chlorine and salt water tend to dry out hair, so anytime you go swimming it's a good idea to apply your favorite Leave-in Crème Conditioner before you swim and give your hair a warm rinse when you get out of the water. 

No, but it is non-toxic and 100% free of all bad stuff.

Yes. This cruelty-free brand is leading the way with quality hair smoothing for all hair types.  We do not list "lamb's wool" as an ingredient.  However, some keratin blends do contain proteins from sheep's wool. Most breeds of sheep need to be sheared at least once or twice a year and they enjoy being shorn.

No, one of the powerhouse nutrients is Wheat Germ which is milled from the edible part of the wheat kernel. 

Using low water pressure, do a 30-60 second light rinse with warm water — do not use shampoo or conditioner. Long, thick, or coarse resistant hair will need a longer rinse up to 2 minutes. DO NOT OVER RINSE but instead leave just a little bit of residue in hair — just like hair feels from a deep masque conditioning treatment (a little slippery).

Yes. The science of KSD does not end with the completion of the treatment. Our unique line of back bar and at-home products are specially formulated to complement our smoothing treatment, as well as continue to improve the overall condition and manageability of the client’s hair.  And, for the folks who have naturally smooth hair and do not require a KSD treatment, our products can be used to help keep their hair healthy looking, manageable and frizz free.  These include:
