Works for me!
So far it appears to be working as my hair has started regrowing after stress hairloss. Great product.

Good bye sticky-uppy-bits!
This stuff smells amazing. The bottle feels luxurious. It keeps you scalp feeling comfy and your hair looking thick and lustrous. But the big surprise? All those little hairs that tend to stick out along the hairline…somehow miraculously gone!

One of the best hair growth serums I’ve tried
I regret to inform that this is an awesome product… it’s one of the best hair growth serums I’ve tried, it’s really made a difference with my baby hairs and my hair stopped falling as much about 2 weeks after I used this product. The only con for me is the price… it doesn’t come with a ton of product and the dropper doesn’t reach the bottom so it’s kinda difficult to reach the last drops.The liquid is very thin and my hair doesn’t get greasy at all as it’s absorbed in a couple minutes after massaging it in my scalp.

Effective and not greasy or heavy on curly, knotty, thin hair
Love this oil. I have curly, knotting hair that is thin. This oil was fabulous to create a soft style. The hair does still knot, but it seems to be the best oil I’ve found. Not greasy at all.
Miranda –
Too little product for the price
Pros: Scent is nice. It’s water-based, so it doesn’t leave my hair super greasy.Cons: This only lasted a week. I don’t really see how this is financially feasible for the average consumer.

LIQUID GOLD!
First time I tried this I fell in love with it. Just not the price. Well after multiple purchases trying to find the perfect dupe for this… I am here to say that this is the best scalp product ever made.Here’s why:1. I have had a hard time finding a LIGHT scalp product. This is light and dries as if you have nothing in your hair. Put it all over your scalp and there’s no residue!2. Wet or dry. Apply whenever. I apply this to wet AND dry hair as needed. If I got an itchy spot and my hair is dry? No problem. Soaking wet? No problem.3. This really helped me with dry scalp. Like – REALLY helped me. Head and shoulders cannot compare. In the winter I get dry patches that are itchy and this heals it so quickly. This also helped when I had tape in extensions. I would apply to the tracks and it would lessen irritation.4. HAIR GROWTH! I never realized how important a healthy scalp is for hair growth. Well now I know. My hair has grown 4 inches in 3 months – and I have fine brittle hair that would show maybe 1/2 inch every 2-3 months.This stuff is GOLD and even though it’s expensive for not much product (I think it’s the packaging that makes it so pricey – but so pretty), it’s SO WORTH IT!Again, I love me a good dupe but there’s nothing on the market that tops this.

Smells amazing. I mostly apply after washing my hair. I believe it also helps with hair falling too. Can see some baby hair. Just need some time to observe
