Will this solve the problem?** A: This isn’t a miracle cure, my best advice would be using aphogee two step protein treatment over this, you could use this as a booster protein treatment. Don’t over do it with the protein treatments as you can terribly damage your hair. If you’re going to use this, please please use a deep conditioning moisturising hair mask after. **Q: Will this help my thinning hair and when do you apply ? after shampooing or after conditioning , and a lot or a little ?** A: I don’t think this will help your thinning hair. I use the product on towel dried wet hair before I use the hairdryer. I do like the product as I do think it keeps the ends healthy. **Q: Can i know how to use this protein treatment serum?** A: Just put a small amount through wet hair after you’ve washed it. Leave it in. Dry and style as normal. **Q: I already use hair tonic so should i use it after my tonic?** A: Tonic is for scalp this is more to give structure to the length . I would use this first on length of wet hair then tonic mid dry /only damp on scalp ## Frequently Bought Together - Charles Worthington Grow Strong Longer & Stronger Protein Treatment, Hair Growth Serum for Fine Hair, Hair Repair Products for Women and Men, Salon Hair Repair, 150 ml - Charles Worthington Grow Strong Scalp Tonic, Hair Growth Serum for Fine Hair, Hair Repair Products for Women and Men, Salon Hair Repair, 100 ml - Charles Worthington Thicker and Fuller Densifying Shampoo, Hair Thickening Shampoo for Fine Hair, Purple, 250 ml --- ## 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/314407372-charles-worthington-grow-strong-longer-and-stronger-protein-treatment-hair](https://www.desertcart.jp/products/314407372-charles-worthington-grow-strong-longer-and-stronger-protein-treatment-hair) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-31*
