research Sterol Intermediates of Cholesterol Biosynthesis Inhibit Hair Growth and Trigger an Innate Immune Response in Cicatricial Alopecia

22 citations , June 2012 in “PLOS ONE”

In this study, researchers found that impaired cholesterol biosynthesis in hair follicles may trigger an inflammatory immune response linked to primary cicatricial alopecia, providing new insights into the disorder's pathogenesis.

research Disrupted cholesterol biosynthesis and hair follicle stem cell impairment in the onset of alopecia

1 citations , September 2025 in “PLoS ONE”

This study found that disrupted cholesterol homeostasis in scalp samples from cicatricial alopecia patients hinders hair regrowth by affecting hair follicle stem cell markers, with resulting effects confirmed in vitro and in animal models.

research Disrupted Cholesterol Biosynthesis and Hair Follicle Stem Cell Impairment in the Onset of Alopecia

November 2023 in “bioRxiv (Cold Spring Harbor Laboratory)”

This study found that disrupted cholesterol homeostasis impairs hair regrowth in individuals with primary cicatricial alopecia by damaging hair follicle stem cells, highlighting the importance of cholesterol in maintaining stem cell function and hair follicle integrity.

research Drought-induced SlCLE10 coordinates ethylene biosynthesis and root hair development to confer osmotic stress tolerance in tomato

January 2026 in “Plant Communications”

This study found that overexpressing the CLE peptide SlCLE10 in tomatoes increased root hair length and improved drought tolerance, suggesting its potential for enhancing crop resilience to osmotic stress.

research Serine Biosynthesis In Human Hair Follicles By The Phosphorylated Pathway: Follicular 3-Phosphoglycerate Dehydrogenase

community Sugars ARE important for hair growth | Glycosaminoglycans as Hair Growth Stimulant

74 upvotes 2 years ago

Glycosaminoglycans are important for hair growth, and combining minoxidil with tretinoin and Biopeptide-CL may enhance hair growth by boosting glycosaminoglycan levels and improving the hair follicle environment. Users discussed the potential effectiveness and future of these treatments.

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 Would you continue to use Finasteride and Minoxidil once HMI 115 becomes available?

5 upvotes 2 years ago

The conversation discusses the potential use of HMI 115 for hair loss and whether it could replace or be used alongside finasteride, minoxidil, and RU58841. The user is experiencing scalp inflammation and continued hair shedding despite using finasteride for 8 years.

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

126 upvotes 3 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 28M experiencing thinning - first timer here, please help

in Treatments 370 upvotes 10 months ago

A 28-year-old male experiencing hair thinning is considering minoxidil and finasteride. Minoxidil helps regrow hair, while finasteride prevents further loss; both are usually lifelong treatments.

learn Hair Fibers

cosmetic product that temporarily makes hair appear thicker

Do hair fibers really make thinning hair look fuller, or is it just an illusion? Hair fibers create an optical illusion of fullness but do not actually thicken hair.
How do you apply hair fibers correctly so they stay in place all day? Apply hair fibers to clean, dry hair and use a setting spray for better hold.
Can hair fibers be used along with medical treatments like minoxidil or finasteride? Yes, hair fibers can be used with minoxidil or finasteride without any chemical interaction.

learn Hair Transplant

Hair transplantation moves DHT-resistant follicles from a donor area (back and sides of the scalp) into thinning or bald areas. The transplanted hair is generally permanent, though surrounding native hair can keep thinning.
