What the gurus are saying

This serum earns praise for calming scalp irritation, especially in people already using minoxidil, and for helping extend the growth phase of hair rather than triggering shedding. The formula feels lightweight without greasiness or tingling sensations, making it easy to layer into an existing routine. Early reports suggest visible regrowth is possible, though most gurus tested it only alongside other treatments, so it is hard to know how much of the result comes from the serum alone.

"When we're thinking about hair and scalp longevity, this is the serum that comes to mind because it's not just about stimulating hair growth, but also making the scalp a more favorable environment to grow healthy hair. The reason I like it is because it helps me tolerate my minoxidil better. Before I started using this, my scalp would get quite itchy with my minoxidil, which I could use a topical steroid for. But once I started incorporating this, I tolerated my minoxidil so much better."

"One Skin, the new Hair Serum that I've been trying for you guys. I love this. I'm using the Klesium. I just finished up my sixth week, seventh week because there's so much in that little bottle. I can get seven weeks out of it. I do my callesium, then I put on my one skin on the days that I'm not using the callesium, and then I'm still using my minoxidil and lowle laser light therapy. This is the newest product in that hair routine. I had no shedding. My seasonal shed was slowed down. All my hair stayed in the antigen phase so much longer. I can attest that. I had not used my I just now started back on my Clesium. So it wasn't that I only used this to give it a really good solid try so that I could report back my honest feedback on the serum. Highly recommend this. And if you need a new Hair Serum and keep your scalp healthy, keep that hair growing and not falling off your head, highly recommend this."

"I have been dousing my hair in this serum and I am really excited to see the regrowth. I'm more banking on the regrowth happening. Hopefully I timed it well enough to get a little bit of regrowth to combat or counteract any hair that falls out postpartum. The formula is great and it's something that's just easy to apply. It doesn't make my hair feel heavy or greasy because some scalp serums can kind of be a little bit too much. It also doesn't have a tingly sensation. It's a really great serum and it has really great reviews. If you just look at all of their clinical studies and actual before and afters, you'll see how effective these are."
