Good but ridiculously overpriced
Ok first things first, this really does work and a little really does go a loooonnngg way. My hair has gone so bad since having my baby that I'm really making a conscious effort to look after it. I tend to a apply one squirt every two days and I certainly notice a difference (softer hair) after I blow dry it. Is it worth the ridiculous price? A little of colum A - a little of column B. Good but in my opinion, overpriced

Better than Olaplex no. 3
This has made my hair feel stronger and bouncier with a few applications. Very impressive. I got the smallest size to try it out following the hype, glad to say it lives up to it.

Like it
Leaves my hair so shiny, silky, healthy. Absolutely love this. The only issue is the price, unfortunately so expensive.

Good (sample size) BUT
An interesting product although I have to say that on my voluminous curly 3C hair I wasn't sure how much product to apply. So far I can't tell if my strands are healthier but maybe I would need a follow up or to further investigate what's a good protocole to have with this kind of repairing product.
