I have never had the keratin treatment at a hair salon, but I use a leave in conditioner, heat treatment and infusion therapy keratin replenisher daily on my color treated hair and I have no issues. Plus the keratin protein weekly on top of all the other products with no issues. **Q: Is is this product most effective when applied to dry or wet hair? many thanks.** A: I think the conditioner is meant for wet hair and this is to apply to dry hair after it's been fixed or blow dried. After I'm done blow drying it, I apply it and it gives it a nice shine. But I'm sure it'll have the same effect if applied to wet hair and then have it blow dried. **Q: You add this to wet hair ? Is this a heat protectant?** A: Yes, you add our unique Keratin Hair Serum on damp hair. Please see the Directions section: "Apply a few drops to your palms and spread thoroughly on dry to damp hair from hair root to tips." It Is a heat protector, although you will see it evaporates as it is water based. ## Frequently Bought Together - VITAMINS hair cosmetics Keratin Protein Hair Serum - Anti Frizz Control Hair Oil Repair Treatment - Gloss Shine & Heat Protectant for Frizzy Dry Damaged Locks - VITAMINS hair cosmetics Keratin Hair Mask Deep Conditioner - Biotin Collagen Protein & Castor Oil Repair for Dry Damaged Hair - Conditioning Treatment for Curly or Straight Thin Fine Locks - VITAMINS hair cosmetics Keratin Shampoo Treatment - Biotin & Collagen Protein with Castor Oil for Curly Wavy or Straight Locks - Sulfate Free Product for Dry Damaged or Color Treated Hair --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/24977558-keratin-serum-with-biotin-castor-oil-and-collagen](https://www.desertcart.tn/products/24977558-keratin-serum-with-biotin-castor-oil-and-collagen) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-23*
