Water in a fancy bottle
Not sure of this product…Is like just WATER in a fancy bottle. Only last me 2 weeks username three times a week only on the top of my head definitely it’s not worth the $65

buyer beware
I bought the hair growth liquid, and it tastes good. I have also purchased the collagen from Spoiled Child.I have been very pleased with both products. I am very disappointed in their hair treatment. It is sent in a heavy glass container (probably for protection). Directions say to shake well and spray 8 times on the scalp and massage. This would be good if any product came out. Opening the tube, and it is a thick gel-like substance that you cannot shake and definitely cannot spray. Many comments have been added about the dispenser. There was no product in the bottle!!! how disappointing

It's a joke
At this point almost two weeks in I am wondering why did I buy this product. It's another one of those it's so fabulous but actually does nothing.

Great shine and feel
Haven’t really noticed a difference in the amount of hair that’s regrowing. But I love the way it makes my hair feel. It gives it a nice shine and bounce without feeling greasy.

Quick delivery and amazing customer service
This seller and product are both 10star. My original was damaged, probably in transit and they helped me with it immediately! I’ve heard great things about it so I’m excited to use it. I did one application right away and could already feel a difference. It didn’t leave any residue like Vegamour or other products. I think it’s going to be perfect! Highly recommend seller!!
