    Did you mean Stem Cell Activity?
    GlossaryStem Cell Activity

    processes where cells divide and become specialized types

    Stem cell activity refers to the processes by which stem cells divide and differentiate into various specialized cell types. In the context of hair growth, active stem cells in hair follicles can regenerate and produce new hair, which is crucial for maintaining healthy hair cycles and potentially treating conditions like alopecia.

      Diffuse hair loss and scalp biopsies

      community Diffuse hair loss and scalp biopsies

      in Research  692 upvotes 3 months ago
      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      community It's over. Hairline has fallen. Millions must shave.

      in Update  467 upvotes 1 year ago
      The conclusion of the conversation is that the user has tried various medications and treatments for hair loss, including minoxidil, finasteride, microneedling, and nizoral shampoo, but has not seen any progress. They have decided to shave their head. Other users suggest options such as hair transplants, RU58841, hair units, and scalp micropigmentation.

      community Rosemary oil's potency as a dht blocker

      in Research/Science  65 upvotes 11 months ago
      Rosemary extract showed high inhibitory activity against DHT, similar to finasteride and dutasteride, but the conversation includes skepticism about its effectiveness in humans since the study was done on mice and rosemary oil is often considered ineffective based on personal experiences. Some suggest trying rosemary oil alongside other treatments, while others emphasize the difference between the extract used in the study and the oil.

      community The theory that explains everything. Please help me make this big!

      in Research/Science  2453 upvotes 3 years ago
      The post and conversation are about the role of the enzyme 3alpha-hydroxysteroid reductase in hair loss and the potential of compounds like procyanidin B2 and sulforaphane to boost its activity for hair regrowth. Further research is needed to develop effective treatments based on this theory.

      community Injecting stomach fat into the scalp could cure baldness in just six months

      in Update  114 upvotes 6 years ago
      A potential treatment for hair loss that involves injecting fat into the scalp; the role of testosterone and estrogen in thinning fat tissue under the skin; research on using lard to treat androgenic alopecia, as well as PRP + ACELL/amniotic stem cell treatments; and ongoing clinical trials by doctors involved in the study.

      community Topical T3 study - 1000% Growth. Anyone tried it?

      in Research/Science  106 upvotes 3 years ago
      The conversation discusses using T3 (triiodothyronine) as a topical treatment for hair growth, with some users noting it showed promising results in studies but lacked follow-up. Users express interest in trying T3 due to its potential effectiveness compared to Minoxidil.

      community SAFFLOWER OIL good alternative for Minoxidil?

      in Treatment  1 upvotes 4 years ago
      Safflower oil is suggested as an alternative to minoxidil for hair growth, with benefits including scalp conditioning and hair strength enhancement. Studies indicate it may also reverse scalp dermatitis, alopecia, and prevent premature grayness.

      community Verteporfin and Microneedling

      in Treatments 5 months ago
      Clinical studies by Dr. Barghouthi and Dr. Bloxham indicate that Verteporfin, when used with FUE and FUT hair transplantation methods, shows promise in hair follicle regeneration and minimal scarring due to its ability to inhibit Yes-associated protein (YAP). Microneedling at depths of 3-3.5mm, combined with Verteporfin, could potentially reactivate dormant follicles, although the optimal dosage and application method are still under investigation. Concerns remain about the DHT sensitivity of regenerated follicles, highlighting the need for further research to optimize trauma levels and Verteporfin concentrations to achieve effective and scar-free hair regeneration.

      community Just started RU a month ago after being on fin and min for almost 3 years. Progress so far: My temples were pretty bare before this. Really hoping at least some of these become terminal.

      in Is this regrowth?  396 upvotes 7 months ago
      A user started using RU58841 a month ago after using finasteride and minoxidil for nearly three years, hoping for hair regrowth at the temples. Other users suggest vitamin B supplements and microneedling to improve hair thickness, and one mentions the possibility of a hair transplant for the temples.

      community Keratin microspheres - breakthrough

      in Research/Science  13 upvotes 8 months 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 Please explain this Minoxidil phenomena

      in Minoxidil  60 upvotes 1 year ago
      The post discusses the difference in effects of Minoxidil (Min) on scalp and facial hair. The user questions why Min-induced hair growth on the scalp is temporary, while facial hair growth seems permanent, even after stopping Min. They propose theories, including different Min mechanisms on body and facial hair, the role of DHT, and the possibility of not achieving fully terminal hair. The responses include personal experiences and theories about Min's effects on hair growth.

      community Anything you use without scientific backing, just trusting your gut?

      in Research/Science  13 upvotes 1 year ago
      The conversation discusses using peppermint oil for hair loss, with one user applying it undiluted to the scalp and another combining it with finasteride and microneedling. Some believe in its effectiveness despite limited scientific evidence, and also mention rosemary oil as potentially beneficial.

      community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

      in Research/Science  732 upvotes 2 years ago
      A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

      FCE 28260: A Forgotten 5α-Reductase Inhibitor

      community FCE 28260: A Forgotten 5α-Reductase Inhibitor

      in Research  330 upvotes 3 months ago
      FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.
