research 641 Evaluation of the influence of sunscreen formulations and SPF on genoprotection in a hair follicle-derived human epidermis model

September 2017 in “The journal of investigative dermatology/Journal of investigative dermatology”

The researchers found that SPF50+ sunscreens provided the highest DNA protection against solar-simulated radiation in a reconstituted human epidermis model, with formulation type not affecting efficacy for a given SPF.

research LB788 Development of a novel three-dimensional human epidermal model from plucked hair follicle-derived keratinocytes

July 2016 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study concluded that a new model of reconstructed human epidermis using keratinocytes from plucked hair follicles offers a less-invasive alternative to conventional skin-derived models for skin research.

research Establishment of a new three‐dimensional human epidermal model reconstructed from plucked hair follicle‐derived keratinocytes

12 citations , May 2016 in “Experimental Dermatology”

The researchers concluded that their new reconstructed human epidermis model from plucked hair follicle-derived keratinocytes offers a safer and simpler alternative to traditional skin-derived models for studying epidermal function.

research A new hair follicle-derived human epidermal model for the evaluation of sunscreen genoprotection

27 citations , June 2015 in “Journal of photochemistry and photobiology. B, Biology”

This study reported that sunscreen with SPF50+ provides a high level of DNA protection against UV-induced damage in a reconstituted human epidermis model, comparable to that in skin explants.

research 138 Characterization of xenobiotic metabolizing enzymes of a reconstructed human epidermal model from adult hair follicles

September 2017 in “The journal of investigative dermatology/Journal of investigative dermatology”

In this study, the reconstructed skin epidermal model derived from hair follicles showed gene expression and enzyme functionality consistent with native human skin, suggesting its viability for studying skin metabolism and potential toxicity of dermo-cosmetic ingredients.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 2 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community My derm said they came up with a new serum that is better then fin? What’s y’all’s thoughts

7 months ago

A new serum claims to enhance hair regrowth by amplifying oxygen delivery, improving the effectiveness of treatments like exosomes and peptides. Users are skeptical, questioning its efficacy compared to established treatments like Minoxidil and Finasteride.

community Keratin microspheres - breakthrough

14 upvotes 2 years ago

A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.

community Comprehensive Microneedling Guide

292 upvotes 4 years ago

Microneedling for hair restoration involves daily use of a 0.3 mm device and weekly use of a 0.5 mm device. Combining microneedling with Minoxidil can enhance hair growth.

community Summary of Procapil video by Haircafe

2 upvotes 1 year ago

Procapil is marketed as a natural hair loss treatment but lacks strong evidence and is industry-biased. Minoxidil and Finasteride are the only FDA-approved treatments for androgenetic alopecia.

learn Platelet-Rich Plasma

What is Platelet-Derived Growth Factor Beta Polypeptide, and how does it help stimulate new hair growth? PDGF-BB is a growth factor that signals to dermal papilla cells and promotes blood-vessel formation; mouse studies report it can push follicles into the growth phase, and human evidence comes only indirectly from PRP trials. No PDGF product is approved for hair restoration and there is no published human trial of PDGF-BB on its own.
