research Histologic Study of the Regeneration Process of Human Hair Follicles Grafted onto SCID Mice after Bulb Amputation

19 citations , November 2001 in “Journal of Investigative Dermatology Symposium Proceedings”

This study observed that human hair follicles with a completely destroyed bulb can regenerate after being grafted onto immunodeficient mice, entering a shortened dystrophic telogen followed by anagen phase.

research A case of antilaminin 332 mucous membrane pemphigoid showing a blister on the bulbar conjunctiva and a unique epitope on the α3 subunit

7 citations , February 2010 in “British Journal of Dermatology”

A woman with a rare autoimmune disorder had a blister on her eye and unique immune reaction, which was effectively treated with medication.

research Immunolocalization of telomerases in human hairs identifies proliferating cells in the bulb matrix and outer root sheath

March 2024 in “Tissue and cell/Tissue & cell”

This study found that in human hair bulbs, telomerase is present mainly in the nuclei of cells undergoing proliferation, particularly in the matrix epithelium during the anagen phase, and sparsely in the outer root sheath during late catagen and telogen phases.

research Effects of epidermal growth factor, fibroblast growth factor, minoxidil and hydrocortisone on growth kinetics in human hair bulb papilla cells and root sheath fibroblasts cultured in vitro

58 citations , June 1987 in “Archives of Dermatological Research”

This study found that epidermal and fibroblast growth factors increased proliferation of human hair bulb papilla cells and root sheath fibroblasts in vitro, while hydrocortisone decreased it and minoxidil had no effect.

research Premature Graying as a Consequence of Compromised Antioxidant Activity in Hair Bulb Melanocytes and Their Precursors

46 citations , April 2014 in “PLOS ONE”

This study found that compromised antioxidant activity in gray hair follicles affects both mature melanocytes and their immature precursors, linked to down-regulation of melanogenesis-related genes.

community Increased shedding with black bulbs after restarting minoxidil

4 upvotes 3 weeks ago

An 18-year-old restarted using topical minoxidil consistently after noticing diffuse thinning and is experiencing increased shedding with black bulbs. Users suggest that shedding is common and may stop with consistent use, but the black bulbs could indicate a strong response to minoxidil.

community Losing hair without the white bulb, Tressless GPT's Response. Do you guys agree?

4 upvotes 1 year ago

Hair loss without a white bulb may indicate mechanical damage, anagen effluvium, alopecia areata, or traction alopecia. Seeking a specialist is recommended, but access can be difficult in smaller areas.

community Read about a recent study on the effects of Agerarin on ex-vivo hair bulbs and...

4 upvotes 3 months ago

The user started using Agerin cream on their scalp and noticed some hair growth, despite not applying it consistently. They also use Minoxidil, RU58841, dutasteride, and finasteride, and have seborrheic dermatitis.

community GFM Gel - High concentration topical gel of Mimicking Growth Factors (GFm), a complex of polypeptides that mimic the action of endogenous growth factors and promote physiological hair regrowth. Helps strengthen the hair bulb and redensify the hair.

6 upvotes 1 year ago

The conversation discusses using GFM Gel, a topical gel with polypeptides that mimic growth factors to promote hair regrowth and strengthen hair. It also mentions treatments like Minoxidil, finasteride, and RU58841 for hair loss.
