I wouldn't say that a pea-sized amount (as suggested) is enough if you have a lot of hair, but I use about 3 pea-sized amounts which is still very little for my thick, damaged hair. It lasts for ages and has a really lovely scent. It doesn't work wonders if your hair is in bad condition, but it does not make it worse and it's not heavy at all. I apply it after I've washed my hair as evenly I can together with hair oil and heat protection spray and my hair is nice and smooth after that. Review: Want to try this? Please Do!!! - I must admit .. I bought this by the power of the advertisement and in a moment of the spending spree.. I was weak!!! But I do not regret the purchase!! My hair are stronger, shinier and with a greater volume. I have noticed that they break less and it looks like they are growing faster and become longer. I have fair hair .. I usually dislike my hair. It's truly tragic to admit that! I will keep using the product. It works for me. I got who tubes! No need to use much - it will last for a while! Real value for the money! It is scented beautifully! Would make thoughtful present ... just saying .. my birthday is approaching.. ## Features - Grow Strong Treatment: Strand building protein serum to boost hair health, making it instantly 6x stronger, reducing breakage by 90% in one use. - Benefits: This reconstruction protein treatment targets the inner cortex to repair hair from the inside out.

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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works excellently and smells lush *by A***X on 17 March 2023* This is a great product, especially for the price!
