  • Honestly one of the best products for growing my hair long !
Size: 10.1 Fl Oz (Pack of 1)
0 bad things. Istg. I’ve had this shampoo since 2025 now because I had a haircut bob in 2025 and now my hair is halfway down my back. Doubled my hair length, is kinda expensive but for how often I purchase it’s very worth it. - I got a short haircut that I didn’t want and was unhappy with and I wanted anything to work. I purchase this and the conditioner it’s a separate one on Amazon’s , and one bottle lasted me over a year. But I also use L’Oréal Paris shampoo aswell every over week (protein overbalance reasons) , and my hair has gone from damaged- to now shiny and I get little to no damage from bleaching. I’ve always had thin hair but now I feel confident with the length. - dont ever change the ingredients🙏 ... show more

  • Would buy again
Size: 10.1 Fl Oz (Pack of 1)
Repurchase. Made my hair feel so clean and it smelled great for days, but it is too expensive to be an every day use and I could not tell it grew my hair.

  • Love it!
Size: 10.1 Fl Oz (Pack of 1)
This is an amazing shampoo. I got a HORRIBLE haircut a few months back. It was incredibly short. My hair was chin length all around. I was mortified. I saw many videos recommending this shampoo to help my hair grow quickly so I decided to try it out. OH MY GOSHHH my hair grew so much and it's so healthy! My hair was chin length in march and 4 months later it's shoulder length! (Ive gotten a few trims for maintenance.) Not only that, it smells great and my bottle is looking like itll last another 4 months! This shampoo combined with some scalp oiling will have your hair growing soft and FAST! ... show more

  • Smells nice
Size: 10.1 Fl Oz (Pack of 1)
Smells very good. It cleans well and lathers nicely. it leaves my hair feeling nice. I've just one bottle so far and just bought a second bottle. I don't know if it is effective yet. It is easy to use. It's a little pricey. I'm hoping it works well.

  • ★★★★★ Leaves My Hair Stronger and Healthier
Size: 10.1 Fl Oz (Pack of 1)
I’ve been very impressed with this shampoo. It cleans gently while leaving my hair feeling soft, strong, and refreshed. The biotin-infused formula lathers well, rinses out easily, and helps my hair look healthier and more manageable. My hair feels stronger after each wash, with less breakage during brushing. The quality is excellent, and a little goes a long way. I would definitely purchase this shampoo again. ... show more

  • GREAT FOR GROWTH
Size: 10.1 Fl Oz (Pack of 1)
AMAZING! Multiple people have commented on how much longer my hair is getting. I felt like I was in a year slump with stagnant hair growth and after consistently using I have seen a great impact in just a month!
