This product may help with scalp health, but it doesn’t regrow hair. My dermatologist said there’s nothing in this product that promotes hair growth. I wanted to love it.

My Staple Hair Serum

This is a staple in my hair routine. I’ve switched on and off to other hair serums to try them out and every time I’m disappointed. Nothing performs better than Vegamour. After consistent use, my results always speak for themselves. I notice a major reduction in hair shedding and my regrowth is very visible.

Destroyed hair! EXTREME shedding & scalp flaking

I purchased this product to help with hair thinning. I have never before had a product that so badly damaged my hair! After I began using the product, I noticed that my hair began to shed a TON. Like, massive piles of hair would be on my countertop after I brushed my hair--and not to mention all the hair that would fall out during the shower. My hair had never shed that badly in my life before. I continued to use the product, though, because it was past the return deadline and figured maybe this was just the "initial stage of shedding" some hair growth products claim is normal before it eventually thickens your hair. I finally stopped using the product after I noticed EXTREME scalp flaking in the areas I was applying the product. This wasn't just dandruff; it looked like scalp psoriasis... literal huge patches of what I think was my scalp were flaking off in chunks, which made it so embarrassing to go out in public for a while. As soon as I stopped using the product, the "psoriasis" I had plus the shedding went away entirely. My hair is now back to a normal shedding amount, but my hair is noticeably thinner from all the shedding this product caused. I could not be more displeased with a product if I tried, especially with the price I paid for this! STAY AWAY AT ALL COSTS!!!

Nope.

Terrible product for the price. I used it for 3 months and nothing. My hair started shedding more. And I saw no results. Save your money, and buy something less expensive.

This actually changed my hair!

Girl please read this!!! I used to not believe in hair growth serums at all, but this one truly proved me wrong. My hair went through such a transformation. I started noticing less breakage, new growth coming in, and overall my hair just felt so much healthier. It was so damaged before and now it literally feels like my hair is back. I even felt confident enough to color it again. I’m honestly obsessed!!!

Absolutely no results. Hair was unchanged after 30 days. Disappointing product.

I’ve been using this for about a month to try thicken my hairline and hopefully add some length. I’ve noticed less hair fallout in the shower, however, I am also using other products that are supposed to help with that too. So I am unsure if it is really making a difference. It also does leave a sticky/greasy residue when i use it, even with damp hair. Overall, for the price I would say to go with a different brand or product because this one does not seem worth it.

Average scalp/hair serum

Watery texture that absorbs well and does not leave a sticky residue on my hair. After 2 months of use I have not seen much difference, not much growth and hair loss is about the same.

The rep was totally convincing WORST MISTAJE I have ever made listening to that rep. I’ve lost so much h hair I now bald spots . I’m 44 years old this was suppose to help me not hurt me even worst!

TERRIBLE PRODUCT

I purchased this product and used it exactly as instructed. The bottle is marketed as a three-month supply, yet it only lasted me two months. I have fine, thin hair, so there is no reason it should not have lasted at least the full three months. Unfortunately, the product did not work for me, and I experienced significant hair loss, shedding in large clumps. Additionally, the dropper included with the bottle is terrible. It rarely drew up the full amount as instructed, and once the bottle was low, the dropper stopped working altogether. When I contacted customer service to address these concerns, I received a generic response along with a 10% discount toward a future purchase. This was not an acceptable resolution, especially since I will not be repurchasing this product.
