Glossary Extracellular Signal-Regulated Kinase

protein that transmits signals from cell surface to DNA

Extracellular Signal-Regulated Kinase (ERK) is a type of protein kinase that plays a crucial role in the MAPK (Mitogen-Activated Protein Kinase) signaling pathway. It helps transmit signals from the cell surface to the DNA in the cell nucleus, influencing processes like cell division, differentiation, and survival. This pathway is important in various biological functions and can be implicated in conditions like cancer and alopecia when dysregulated.

community New Research- Creatine Increasing Scalp DHT Without Corresponding Serum DHT Increase

121 upvotes 2 years ago

Creatine may increase scalp DHT without affecting serum DHT, potentially speeding up male pattern baldness (MPB) for those genetically prone. Treatments mentioned include Minoxidil, finasteride, and RU58841.

community Peptides that Stop Hair Loss? | In-depth Literature Review Video

76 upvotes 2 years ago

Peptides like TB500, KPV, GHK-CU, and BPC-157 are overhyped for hair growth with limited proven effectiveness in humans. Combining peptides with delivery methods like iontophoresis and sonophoresis shows promise, but many claims remain unproven.

community DHT Harms Scalp Microbiome: DHT Itch is REAL

413 upvotes 1 year ago

Increased Malassezia and Cutibacterium in the scalp microbiome are linked to higher sebum production and inflammation in androgenetic alopecia (AGA). Treatments include ciclopirox shampoo, benzoyl peroxide shampoo, clobetasol propionate, calcipotriol, minoxidil, finasteride, and dutasteride.

community We already know how to permanently fix hair loss. The science is done. The only thing missing is the funding to run one experiment.

in Technology 613 upvotes 4 months ago

A permanent hair loss solution could involve reprogramming hair follicles to resist DHT using mRNA and siRNA. However, high costs, safety concerns, and the pharmaceutical industry's preference for ongoing treatments over one-time cures are major obstacles, with finasteride and minoxidil remaining standard treatments.

community My Theory Of Androgenic Alopecia

16 upvotes 9 months ago

Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
