It’s ok.

It's not bad, but for the price, I expected something much better. There are masks at half the price that are much better.

Disappointed

it’s not worth it tbh. I’ve purchased this in July 2025 & it has done nothing to my hair, i’ve tried different shampoos and stuck with this same hair mask and i still didn’t notice any difference, the only thing it did do was soften it up but nothing major. & the consistency of it is very thin it almost feels like a thick water consistency if that make sense, but yeah it’s really not worth the amount at all, i’ve tried cheaper alternatives way before.

Smells amazing

Made my hair so shiny, soft, and silky. Also the smell is divine. I have fine, pin straight hair and it worked really well for me

Even great in men’s hair!

I damaged my hair a little bit from heat styling and my hair needed a pick me up, just from one use of this mask I saw a change! My hair was noticeably more manageable and less frizzy. A little goes a long way too! Get it!

Waste of money.

It doesn’t do absolutely anything to my hair… I feel like is a waste of money. It’s smells really good but it doesn’t even work as a conditioner. Totally dissatisfied.
