Strengthening Biotin Treatment for Long Hair Redken Extreme Length Leave-in Treatment

Very cool product, one of the few that is perfect for my naturally curly, stiff and prone to dryness hair. The only downside is the price. I bought it in December with a discount on makeup for 550 UAH, but now the price has doubled.

Thin, delicate hair. Burned by bleaching, currently growing it out. And this is the best thing that could have happened to me in six months. 10 out of 10.

I really liked it, my hair feels fuller and not dry. I recommend it for blondes.

I tried it, it reminded me of the leave-in elixir from Matrix Total Results So Long Damage Break Fix. It makes the hair silky, by the way, I tried a little bit on dry hair and rubbed it in my hands, I'm satisfied with the result so far.

I didn't like the product on my hair. No softening, no shine... My hair is not dyed, porous, and thick. The effect is better and more noticeable after using oils. The smell is normal, light, but it doesn't last long. It's too early to talk about the results, I will use the entire tube and then we'll see.

I didn't see any result at all, and the smell is disgusting. It's a waste of money.

Good, but I used it in combination with Redken balm. Hair is soft, it makes them easier to comb, it just softens them, but it doesn't give shine... only if used in combination.

Good quality product. For thin hair, you need to apply a very small amount, as it can weigh them down. But this is a characteristic of the hair.

Great product! I received a sample as a gift with my order and I can't get enough of it. My hair feels full and strengthened, I can already feel the difference after the first use. I'm eagerly waiting for my colorist's feedback, I think he will like the condition of my hair.

Liked it. Gives hair a filling effect. Hair seems to become thicker. Can make hair a little greasy if overused.
