Gone are the days when smooth meant limp, poker straight hair. Our revamped TRESemmé Keratin Smooth Collection, now with a color-treated system and enhanced hair smoothing products , is specially designed to fight frizz, detangle knots, boost shine, add silky softness, and tame those pesky flyaways. When it comes to smooth hair, keratin products are a must. That’s why we recommend to cleanse and condition with TRESemmé Keratin Smooth Shampoo & Conditioner to transform dry tresses into enviably smooth, sleek locks. Treat dry hair to a TRESemmé Keratin Smooth Mask for a head-turning shine. Tame frizz and control flyaways with TRESemmé Keratin Smooth Frizz-Free Hold Hair Spray. To protect your color with keratin for hair, use our new Keratin Smooth Color system with Argan Oil for color-treated hair that has radiant shine and vibrant color.
