How To: When to Reapply Keratin

Frizzy hair can be frustrating. But with keratin treatments, your hair can go from frizzy to straight in just a few hours! Unlike ironing, relaxing and blow-drying, a keratin treatment is much gentler on your hair and scalp.
But what happens to hair after keratin treatment wears off? Keratin treatments are rejuvenating for hair, and will bring the shine and brilliance back for months. Eventually, it will wear off and you’ll slowly lose the amped-up keratin levels. At that point, it’s time to reapply.
