The real deal!

Tee Jay—June 24, 2025✓ Verified purchase

This product from SickScience Labs has proven to be remarkably effective! Just a month ago, I was dealing with a bald spot on the top of my scalp that measured about 1/4 inch in diameter for 15 years. I tried from Microneedling to other hair growth products with little to no real success in this bald spot area. But since using this product, I've noticed significant regrowth, with Vellus hairs—often referred to as baby hairs—starting to fill in the area, which has greatly diminished the visibility of the bald spot. My barber has also confirmed this positive change, noting the improvement in my hair's overall appearance. Additionally, I've observed a marked increase in hair thickness in areas that were previously thinning. I wholeheartedly recommend this product to anyone facing similar hair concerns. A big shoutout to SickScience Labs for their incredible work! Thank you! Read more

Don't believe the hype!

Strongarm—January 22, 2026✓ Verified purchase

Eh! Clearly this product is not for natural coily hair in my opinion. It has left my hair texture more frizzy than it already is. The serum has the viscosity of slime and on the scalp it feels like it is clogging the pores. For the expense spent on one bottle to me it is not worth it so, I canceled my subscription for automate delivery. I could not even get a refund 😠 Read more

This product takes a long time to dry and leaves white flakes in your hair. I stopped using it after 2 nights. I missed the Return Window so I'll have to throw it away. It was a waste of my money. Read more

High-quality scalp treatment serum. The serum is in a really cool, shiny bottle that has a dropper dispenser for convenience. It’s lightweight, and so hydrating. Absorbs quickly and leaves hair shiny, and soft. The serum works well, and is a great addition to any hair care routine. Read more
