Frequently Asked Questions

Keratin Salon Direct (KSD) smoothing treatments are
transformational, long-lasting and safe treatments that bring hair to its
ideal, most beautiful condition without damaging or dangerous chemicals like
formaldehyde, which can be found in other straightening or smoothing products.

AnswerOur SMOOTH product, which requires the use of a flat iron, delivers
straighter results than our FLAT IRON FREE EXPRESS product. Many users of our
SMOOTH product prefer it to Brazilian salon keratin treatments. The primary
difference between our two treatments is that FLAT IRON FREE EXPRESS does not
require the use of a flat iron and SMOOTH yields a straighter result.

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

Yes. It is best to color hair after the treatment. This eliminates
any problem that may occur related to lifting of color. If you color after treatment
it can be done the same day or anytime after. If you color before the
treatment, like all smoothing treatments, some color may be lifted and highlights
may be brighter.

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.
