This shampoo smells AMAZING!!! it's cleanser my very oily hair so well! Did I mention that it smells AMAZING 😄 It has a clean, citrus fragrance. A little goes a long way. I have short hair and it use a little less than a penny-sized amount. I highly recommend that you purchase the hair serum/solution as well. Together they make a great team which leads to my hair feeling healthy. Highly recommended!

After a terrible haircut—chopped and uneven—I was desperate to find a way to grow my hair out. I dove down the TikTok rabbit hole and came across an influencer promoting this product. Honestly, I was skeptical, but decided to give it a try. I’m so glad I did! My hair has grown significantly, the shorter ends have grown out enough to blend like layers, and the shedding has stopped. Plus, it leaves my hair incredibly soft and full. Truly a game changer!

I think this shampoo is worth your money. Paired with the conditioner, it leaves your hair soft and smelling nice for a long time, and it doesn't make your hair feel greasy or heavy at all. It also has a little bit of a cooling effect on your scalp, which I really like. I never really paid attention to the hair growth, so I can't say whether it works for that or not.

I honestly did not know a shampoo could make my hair feel like this! It’s a luxurious experience and I genuinely feel the cleanse and moisturizing that I see people write about other shampoos. It’s lasting me quite awhile because it doesn’t take much and I feel it’s improved my hair and scalp health effectively.

Excelente producto para el cabello

I’ve had this shampoo and I can feel the difference. My hair looks healthier and thicker. I am using minoxidil on top of this and most of my bald spots I had are either gone or close to being gone. The price of the item is quite high but I’m getting results so I can’t really complain.

Love the smell and I love how clean my hair and scalp feel after. It does dry up my hair a bit during the application but after doing the shower treatment and applying conditioner, it's feels so smooth.

Great product. I can see a lot of difference from before using this product and after. My hair have never felt so heavy and full and soft
