community Shiseido Dermal Sheath Cup (DSC) Hair Multiplication Is Finally in Japan (on July 1)

in Treatment 25 upvotes 2 years ago

Shiseido's Dermal Sheath Cup (DSC) Hair Multiplication treatment is now available in Japan. Users discuss the treatment's availability and cost.

community Shiseido filed for this patent in May 2019. Let's get some big brain discussion on this.

4 upvotes 6 years ago

The conversation discusses a patent filed by Shiseido for cloning Dermal Papilla (DP) cells to treat hair loss. The method involves using viral vectors to maintain the cells' growth-inducing properties, differing from Replicel's approach with Dermal Sheath Cup (DSC) cells.

community Has anyone here actually tried Shiseido’s S-DSC hair regenerative treatment in Japan?

in Technology 13 upvotes 3 months ago

Shiseido's S-DSC hair regenerative treatment in Japan focuses on improving existing hair by thickening miniaturized follicles, not creating new ones. There is limited patient feedback and long-term data available.

community Has anyone here actually undergone experimental (grey market) hair cell therapy/follicle cloning?

in Technology 6 upvotes 3 months ago

Hair cell therapy and follicle cloning are still in experimental stages, with treatments like hair multiplication and regenerative hair therapy being marketed but not yet proven to create unlimited new follicles. There is skepticism about the effectiveness and legitimacy of these treatments, with some considering them scams.

community Hair loss research focused on chemistry for decades because we misunderstood the mechanics of growth.

in Research/Science 48 upvotes 5 months ago

Hair growth relies on mechanical forces, not just chemicals, with tissue acting like a motor. Minoxidil and finasteride help, but maintaining tissue elasticity and addressing mechanical issues are essential.
