Types of Keratin Treatments
1. Brazilian type salon treatments that deliver straighter hair that lasts for months and frequently use formaldehyde with average cost of $250
2. Formaldehyde free salon treatments are about the same price but not quite as effective or long lasting.
3. Salon Express Treatments — Less expensive than the Brazilian or standard formaldehyde free type treatments. Express treatments may or may not contain formaldehyde. They last for several weeks and cost on average $100-$300
