OS-01 HAIR Peptide Scalp Serum is a daily treatment designed to nourish the scalp and support the hair’s natural growth cycle. Powered by the brand’s proprietary OS-01 Senescence Blocking Peptide™, it targets a root cause of hair thinning by helping to reduce the accumulation of ageing cells that disrupt healthy follicle function.

Clinically shown to improve hair density by up to +40% in six months, this lightweight, fragrance-free serum strengthens the scalp barrier and promotes an optimal environment for growth. A blend of Panax Ginseng Root Extract and Biotin helps energise and fortify strands, while Fisetin and Sunflower Sprout Extract protect against oxidative stress. Rice Bran Water, Inulin, and Alpha-Glucan Oligosaccharide help balance the scalp microbiome, reduce dryness, and enhance hydration for healthier, fuller-looking hair.

Dermatologist tested, vegan, non-comedogenic, and safe for sensitive skin, OS-01 HAIR Peptide Scalp Serum is 100% free from fragrance, parabens, sulfates, and other unnecessary additives, giving you a simple, effective way to care for your scalp and support visibly healthier hair every day.

Feel so clean!
Size: 5.3 Ounce (Pack of 4)
The packaging is amazing, each bar has it's own unique odor. I was stuck on another companies product for nearly 2 years and I can see me purchasing this product again.

Quality Men’s Soap
Size: 5.3 Ounce (Pack of 4)
I purchased this bar soap for my three grandsons and my granddaughter’s boyfriend. They are all in their 20s and liked the fact that the soap lasted longer than the soaps they usually use. I did give them each a different scent and they appreciated the fact that the scent was not overwhelming, but subtle. Generally speaking, young men this age usually do not purchase quality soap or personal hygiene items mainly because of cost. They all were very pleased with the surprise gift and proceeded to use it immediately. I would compare it to the expensive Dr. Squatch bar soaps. I bought these on sale and felt like I had gotten a very good deal. It is a pleasure to give someone a gift that they normally would not purchase themselves. I will continue to shop this website for future purchases and wholeheartedly recommend Rinse and Robust Men’s Bar Soap.

Smooth Bars are nice, Scrub Bars Too Rough
Size: 5.3 Ounce (Pack of 4)
Not bad soap. The scents aren't overbearing, but the "Scrub" style bars.... I have very little use for other than the bottoms of my feet. They are extremely rough and not for use directly on the skin. I've other "scrub" bars in the past that I could use almost all over the body but these are like lava rocks.

Great Scents
Size: 5.3 Ounce (Pack of 4)
Each of the 4 bars smells fantastic. To this point, I have only used one of the exfoliating bars, but it feels great on the skin and does not leave any residue. Also works great on my beard.
