My Fave!!
About 9 months ago I was sent this shampoo, conditioner and leave in treatment to review by a third party company. I have to admit, the first thing I noticed was the scent. It's marvelous!! The second thing I noticed is that after a couple of uses, my hair didn't break near as much. There wasn't a l...

Scent is wonderful, overall product not as much
I received this product to try for free in exchange for sharing my opinion about it. I have fine hair that lacks volume, as well as certain pieces that don't really seem to be growing at all, so I was very excited to try this product. The first thing that I noticed about it was the scent. Wow! This ...

Smell pretty good
Hair Type Wavy Hair
I brought this shampoo and conditioner as a set a long with the leave in conditioner as I apply for the first time it left my hair super soft and refreshing look. I had to buy me the bigger bottle
Absolutely love ❤️
Why is this line getting bad reveiws? This is amazing shampoo, it lathers, cleans, volume bouncy, and my hair feels and smells so good. I dont need a leave in because it detangles my very long fair to meduim hair, this is highly recommended by me. My hair is blunt past my waiste! And its glorious shampoo and conditioner💖
holy grail shampoo.
Okay so i chopped off a LOT of my hair in january 2025, i was rocking a lord farquad cut for awhile… i picked this up in late february. Let me just say, yes it is drying. But thats okay! maybe not for everyone else but for me it is because my scalp is extremely oily and i learned that if i double shampoo with this product only it makes me hair so soft and shiny and clean. I just learned about the whole double shampoo thing and it has made my scalp sooo much healthier i really recommended doing that it's made my hair super thick and strong. I also do NOT use this brand's conditioner it just doesnt work for me i have very fried ends from hot hair tools and dying my hair a lot my whole life (which i also stopped doing in january) so i use it's a 10 hair mask religiously it works well with my hair type. My hair type is striaght/wavyish. My hair has grown so much i like to think my hair grows at a normal rate on its own but because i've fried it off so much i dont think it grows that willingly anymore. With this shampoo it does. No my hair has not broken off or fallen out and no it does not burn my scalp! i think this product is something you need to try for a month straight and really see how it affects you. It's been almost 5 months and my hair is now just reaching past my shoulders when in january it was right below my chin. I love this shampoo i will not use anything else. I mainly started to use this so i could grow out my natural hair color i have brown box dye on my hair and my natural hair color is dirty blonde. I can't wait for it all to grow out i honestly think by next summer it will be all grown out and i can finally cut off my boxed hair dye and just be all natural again. Anyways give it a try if you have similar problems like me i wish you luck!!!
I would not buy again
Hair Type Straight Hair
I used it two times and both times lots of hair came off . Made my hair fall off.
I LOVE this shampoo!
Hair Type Wavy Hair
I love this shampoo! It makes my hair soft but does not make it greasy by the end of the day. I have fine hair that gets greasy easily. It also gets tangled easily. This product is great! And it smells SO VERY GOOD. Not overpowering and very clean! I would buy it over and over!
