Residue
The price is right, but it leaves my hair at the front/crown greasy looking. Definitely builds up in the hair.

Would recommend!
I bought this proct cause I was getting extensions and wanted to combat any hair loss or traction alopecia. I've been using these drops alternatively with the Cecred Edge drops, and in three months my hair has visibly grown faster then is normally does and apesrs fuller. Was amazed at my last extention move up how great my natural hair looked on its own. Dont know if I can say if I have new demsiyu but it's definitely helped with growth and shedding.

Game Changer for Thicker Hair
Had to write review in hopes of helping someone else. I have fine thin hair and had hair loss and thinning edges due to iron and other issues. Tried Cecred (no knock to whoever it worked for) with no results. Tried this and while I didnt see edge regrowth, my hair is much fuller after a month of use. I use 2-3 times a week on crown and through scalp from front to back and use a scalp scrubber to massage into head. I will be keeping this as a staple product. My confidence at seeing my hair fuller is back! Love it!

Impressed with results
I'm 40 with fine, thin hair that I have damaged with bleach. I have some hair loss at the corners of my hairline, like mini bald patches, and I had noticed a lot of hair falling out in the shower and on my brush. I have a lot of family history of hair loss in men and women. I have been using the Hair Density Serum every night for a month now, and dermarolling my scalp with a .5 mm dermaroller before application every other night. I have almost no shedding in the shower now! I even bleached and colored my hair and had very little fallout. I am noticing hair growing back along my hairline and in the balding spots. My mom, who sees me every day, even commented that my hair looks thicker. It does feel a little weird/sticky when you first apply it, but it seems to dry quickly and is fine in the morning. It also goes fast, so the bottle doesn't last as long as you might expect. Other than that I'm really happy with this product and would definitely recommend it.

AMAZING
I just started using this serum two weeks ago. After applying it consistently 3-4 times a week, I can already tell the difference in density and health. Apply it directly on your snap and massage through. I dont feel like it makes my hair excessively greasy, as someone who already has somewhat greasy hair.. its nothing dry shampoo cant handle!! Reminder: you're not going to see growth specifically with this. This serum is to improve the health of your follicles and promote density. However if you think about it HEALTHY SCALP = HEALTHY GROWTH 😃

Never leave reviews, but needed to for this!
Been using this serum since Dec 2025 & the biggest difference I'm seeing is that it has decreased hair fall out by almost half! Haven't noticed baby hairs but my hair is growing length wise! Also use it with the Abbey Yung method & my hair loves it

It works very well for me
I have natural type 4 hair. I have been battling with traction alopecia for about 10 years. And my hairline is filling in very nicely. I'm so pleased. My advice is to stop the high tension hairstyles ASAP. Use this on your edges. Keep your scalp clean have a good routine and massage your scalp as much as possible. Take your vitamins drink your water and have a good diet.

Actually works
Hair broke off after getting braids. Been using these drops on average 4 times per week (mainly because I forget to use everyday). These results are within 3 months and I still have about 1/4 of the bottle left.

I’ve been using it for about a week, so it’s too early to see visible results. The texture is lightweight and doesn’t make my hair greasy. I will update my review after a few more weeks.

Do not waste your money
I brought the 2 oz bottle and used it religiously for 2 months and did not see any change what so ever. It was like water and did make my hair little greasy. DO NOT WASTE YOUR MONEY.

Can work for some, just not for me.
The product was okay for me. I had used this product for about a month and so on. I did see some growth but not as much as I saw compared to the reviews. As I was using it I found it left mg hair oily and a risduse after. However, the product I feel is the type to work on some but not all.

Works but you have to use it forever to keep results
Works pretty well - but if you stop using it, all the hair growth will fall out. It was terrifying while it was happening, I went and got blood tests because my hair was falling out when i didn't bring it in vacation for 10 days!

Works
I have hairloss and breakgae mostly due to anemia but I also have stress telogen effluvium. This visibly shrunk my widening part in about 2 weeks, reduced hair fall started right at the end of a small bottles use. Not a miracle, definutely helps. Cheap.
