Buy this

This product works!!! After trying several other hair regrowth products with no success I tried Zenagen and it brought back my hairline and thickened my overall hair. It has also greatly decreased my hair shedding. I am so glad that LovelySkin sells it because they are my skin and hair care source. Why shop anywhere else?

3 Weeks and No Complaints

I bought this when I noticed significant hair thinning/scalp exposure and have been using it only about 3 weeks in combination with red light therapy but so far I think it has helped in less breakage and strands looking a little fuller. I am excited to see if extended use helps more!

Liking this so far

I am enjoying using this hair serum. I am also using the shampoo and conditioner so not sure what works best. But I am seeing new hairs at my hairline which is promising! It is lightweight and doesn’t grease up my hair.

Hair Growth

After surgery my hair stated fall out in clumps. My hair is growing back and seems thicker. Can’t wait to go to my hairdresser to see her opinion!

This stuff works

I have menopausal hair thinning so I use the shampoo and conditioner every other shower. In between shampoos I use this daily. It doesn't leave a residue so you can use it without worrying about any greasy or strange film on your hair, and it smells so clean and nice.

Better Than the Minoxidil

I've used Minoxidil for years but noticed lately that is was causing my scalp to itch. I saw the Zenagen serum and thought I d give it a try. No itching and my hair seems fuller only after a week. I d love to try the shampoo but it's very expensive so maybe when it goes on sale.

Less shedding

My hair stylist noted I have less shedding after just using for 8 weeks, that is the time between appointments. I will continue to use this product line. It does not effect my blonde hair.

Happy So Far

I just started using the serum in the evening. I’m using this product in conjunction with the shampoo and conditioner. I like it so far. Only time will tell.

Good hair serum

I have used other hair serums for thinning hair which didn’t do much. Zenagen seems to be working, I just finished my first bottle and started the second one. There is some new hairgrowth with this serum, especially around the temple area. Will continue to use.

Actually works!

I’m a 67 yoa woman who has always had fine hair. It’s never really been thick but when I hit menopause it really began to thin. My hairdresser recommended this product as well as their shampoo & conditioner. I decided to give it a try. It took probably a month before I began to notice a bit of a change. I wasn’t sure what I was seeing, but it appeared thicker. I think initially, it was working to minimize my hair loss, But as I continue to use the products, I began to notice new growth. I’ve been using it for six months now and have definitely seen a change. While it’s expensive, it doesn’t take much of the serum (an eye dropper) or the shampoo (it lathers really well) so it lasts a long time. It works so well that my 30 yoa daughter (who had some thinning from over use of extensions) is using it as well and she has also noticed thicker healthier hair. I’d recommend to anyone who might be facing similar issues.

Very Good Product

I have been using this product since August 2024 and I have been noticed new growth in the area of my edges. Due to wearing braid extensions for years my hair started thinning along my hairline. So after a year of refraining from braids, I’ve including this serum as a part of my hair routine. After 3 months I’ve noticed that my hairline started growing “baby hairs” and my hair line is filling back in. This serum has been very helpful in my hair growth journey. Also as I continue to use the product, I have not been wearing braid extensions {now I only braiding my natural hair without the extensions}.

This is working!

I was originally introduced to this product through my hairdresser and I was purchasing it at the local salon. I was very happy to see that LovelySkin had added it to their inventory and I am grateful when they run a special on it and I can get it at a discounted price. Just so you know changes do not happen overnight, but like I said, I have been using it diligently for about six months. Also make note that I do not use it every day and a couple times a day as the instructions say otherwise I probably would've had results sooner possibly. I use it four days a week once a day. That is just the schedule that works good for me. I suffered an immense amount of hair loss over a year time frame and this along with the shampoo has helped greatly. I definitely will continue to buy it And I highly recommend it.

Sticky

Leaves my hair with a sticky residue so I use it overnight when I know I’m going to shampoo that next day. The serum in combination with the shampoo seem to work well on new growth and thicken up my hair. FYI not a fan of the conditioner, I use a different brand.

This stuff is great!

I definitely think the serum works to thicken hair. You can use on wet or dry hair and it doesn’t leave you feeling greasy or oily, or leave any visible residue. My only complaint is that the dropper doesn’t always work super well to distribute the product in my hair. But overall 100% worth it!

Zenagen Serum

After 2 months of using the serum daily it worked. I am continuing using to avoid more hair loss. Thankfully my hair is returning to better hair. Was so scared. Thanks Zenagen.
