I've been using the shampoo and volumizer for week or so now. Love 'em both..both have the AC-11 ingredient very high up on their ingreds list..and contain other beneficial ingreds(hops, rosemary, nettles etc).

A review:Activar AC-11 is the first product to combine proven DNA repair science with a proprietary organic extract, to create a unique supplement that stimulates your body's natural ability to reproduce healthy cells
Other quotes:THE PILL: Pierre Michel RepHair THE CLAIM: AC-11, a proprietary extract of Uncaria tomentosa (the cat's-claw plant from the rain forest), repairs damaged DNA in hair cells to reduce dryness, thinning, and breakage while increasing shine and thickness. COST: $24 for a 30-day supply GLASSMAN SAYS: "Oral supplements can only affect the new hair growing in. Hair ends are old and dead, so applying a treatment would be better for dry, split ends. And while cat's claw is anti-inflammatory and anticarcinogenic, there's not enough research to show any benefits for hair." MC EDITORS' VERDICT: Our tester's mane felt thicker and fuller after one week and held up to multiple blowdrying and flat-ironing sessions without drying out. After three weeks, she started noticing new growth along her hairline and received at least one compliment a day about how healthy her hair looked. BOTTOM LINE: ****1/2
Two new substances, AC-11 and Dimericine, appear to enhance the DNA repair capacity of cells. These substances might have use in treating patients with xeroderma pigmentosa and in enhancing the ability of sun blocks to prevent ultraviolet-induced cellular damage.
AC-11 is the successor compound to C-MED-100[R] the first nutraceutical having FDA permission to claim natural DNA repair activity. AC-11 is a Cat's Claw (Uncaria tomentosa) water extract that is claimed to be a highly effective antiaging treatment of skin because of several mechanisms: NF-kB inhibition blocking inflammatory cytokine production (eg, TNF alpha), antioxidant properties via electrophilic scavenging and NF-kB inhibition reducing surface peroxides, and enhancement of DNA repair by reducing macromolecular expression and damage and decreasing cellular replication of damaged DNA. When AC-11 is applied topically to skin it decreases the number of "sun burnt cells" and pathogenic DNA dimers induced by ultraviolet light. AC-11 can be taken orally or applied topically. It is made by Optigenex Inc
Finally, in a in a single-blind, right side-left side, beach sun exposure pilot study that included 42 healthy volunteers there were dramatic and significant (p < 0.0001) reductions in erythema and blistering in volunteers who applied 0.5% topical AC-11 with and SPF-15 sunscreen when compared to the group who just applied an SPF-15 sunscreen
