I used it , it made my hair feel great but in the morning I find my hair to be dry and it feels like I didn’t put anything on it and as far as hair growth I don’t see it . And it did not make my hair any stronger it’s still breaking .

Wait to see
I am just starting to use it and I have to use it for a couple of weeks to help me know if it’s works but what I notice after applying it to my hair it’s just makes it so smooth and soft

a miracle in a jar
Scent: Earthy, Nutty, Refreshing, Size: 4.06 Fl Oz (Pack of 1)
This item did exactly what it was expected to do, and I couldn’t be happier with my purchase. It works as described, is easy to use, and the overall quality exceeded my expectations. The price was great for what you get, making it an excellent value. Everything about it—from performance to convenience—has been spot on. My sister has noticed an extreme growth in her hair since using this product. I’m very satisfied and would definitely recommend this to anyone looking for something reliable and well worth the money!
