    It works!

    I bought this hair serum not expecting very much (I have "old-soul" hair and tried every thing). I'm pleasantly surprised. I've used Minoxidl before but it was too heavy and greasy which I hated. I've been this serum it for 3 months now; I see my bald areas filling in nicely (pics to chuckle at) and the rest of my hair has grown out really long. It's not instant; however, it does work. The smell is fresh and light (I get compliments often on the smell), and the fluid itself is lightweight so I don't feel like I need to wash my hair often. Would reccomend

    Hair grew 2 inches!!!

    Absolutely love this serum it not only made my hair feel thicker but it gave it a beautiful shine and grew it like a lion. I used it on dry hair throughout the week and saw more fuller hair and my scalp looked hydrated and so much healthier. I have super fine hair and this help me so much with that. I always am gonna reach for this. It didn’t weigh my hair down at all and never left my scalp or hair greasy which is always a concern for me this serum is a a plus in my book

    Really lightweight, love it 🙌🏼

    I've been using it for 1 month, previously used OUAI and it left my hair way too dry and flakey. I like how light this one is, feels like water. I can wear it daily without washing my hair. I can start to see baby hairs sprouting on my hairline. I love the bottle design by the way, it feels really classy

    Not just baby hairs - it works!!

    This review is long overdue but given the rate of natural hair growth I wanted to ensure it wasn't just fuzz, baby hairs, or wishful thinking. I first started by buying three bottles and planning on using that until the three bottles were gone. My plan was to compare the before and after pictures which seemed a reasonable length of time given that hair only grows 0.5 inches per month. However I'm actually midway into bottle 2 and I have approximately 2 inches of hair growth total. That is TWICE of what you are supposed to get which is just incredible. I use this everyday and I massage in. The first month was really slow but the 2nd month gave me most of the growth. I stopped shampooing everyday so I am not stripping hair of its natural oils. Overall I definitely recommend this.
