Women's Health Mag: 10 Best At-Home Keratin Treatments For Straighter,
Schlepping to the hair salon to get a keratin treatment every four weeks is not only annoyingly time-consuming, but also incredibly expensive. Enter: At-home keratin treatments. They’re inexpensive, easy-to-use, and can be done in your own bathroom.
Of course, there are downsides to DIY-ing your keratin treatment at home. “At-home [keratin] treatments are not as powerful, as they coat the hair rather than altering the structure of the hair, so they generally only last a week at most,” says celebrity hairstylist Andrew Fitzsimons. On the other hand, salon keratin treatments are much more expensive (around $300) but will last you at least one month.
When purchasing an at-home keratin treatment, Fitzsimons suggests looking for formulas that are formaldehyde-free. “Formaldehyde is a harmful gas that is considered to be a carcinogen,” he warns. “If you have thicker strands, you should also look for a formula that adds moisture and shine, while damaged hair could use more softening and smoothing ingredients."
