Preface: my hair is very long, thick and straight. I also have bayalage colors on the ends- so this also makes my hair somewhat dry/damaged. I wanted a product that would help strengthen the roots and also help with split ends. I have used Olaplex before this but I felt that Olaplex was not as effective anymore. Finally, I only wash my hair once a week. I did a lot of research on all of the available hair products that would my type of hair. I settled for Kerastase. I will also like to add: to make sure that this is effective for you, understand that their are companion products to this that make it work. Not only just the shampoo, but the conditioner and the hair serum afterwards (see photos). So develop a routine of using these 3 products and it will work. They all smell great (clean, almost cucumber smell) and they all are lightweight and don't weigh down my hair. My hair feels sleek and stronger compared to olaplex or store bought shampoo. CON: the size/amount of the shampoo. Since I have long hair, i use a lot of product. It lasted about two months. But again, I don't wash my hair everyday. Since this seems like a Euro-derived product, I will look at how much it is when I'm on that side of earth to see if it is cheaper. But I would recommend trying it.

My Jay feels smooth and strong ### ⭐⭐⭐⭐⭐ Helps grow your hair fast!! *by R***N on July 13, 2025* For anyone who is looking to grow out their hair, this shampoo is a must have!! I understand the cost is high, but I have tried so many different brands, wasted money on different products, and nothing has really worked. This shampoo in less than 3 weeks had all my baby hairs growing, my hair felt stronger and softer. It’s expensive, but you will love your hair so I think that’s worth it. ## Frequently Bought Together - KERASTASE Resistance Bain Extentioniste Shampoo | Length Strengthening Shampoo | Protects Hair and Scalp from External Aggressors | With Ceramides to Enhance Shine | For Damaged Hair - KÉRASTASE Resistance Ciment Anti-Usure Conditioner, Repairing Anti-Breakage Conditioner, Repairs Damaged Ends formulated with Pro-Keratine Complex for All Hair Types, 6.8 Fl Oz --- ## 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.jp/products/81307588-kerastase-resistance-strengthening-shampoo-for-damaged-hair](https://www.desertcart.jp/products/81307588-kerastase-resistance-strengthening-shampoo-for-damaged-hair) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-20*
