research The Effects of Lower vs Higher Cell Number of Platelet-Rich Plasma (PRP) on Hair Density and Diameter in Androgenetic Alopecia (AGA): A Randomized, Double-Blinded, Placebo, Parallel-Group Half-Scalp IRB-Approved Study.

6 citations , May 2021 in “Aesthetic Surgery Journal”

This study found that intradermal injections of platelet-rich plasma were equally safe and effective for treating androgenetic alopecia, with higher platelet numbers possibly enhancing hair density and follicle diameter.

research Commentary on: The Effects of Lower vs Higher Cell Number of Platelet-Rich Plasma (PRP) in Hair Density and Diameter in Androgenetic Alopecia (AGA): A Randomized, Double-Blinded, Placebo, Parallel-Group Half-Scalp IRB Study

June 2021 in “Aesthetic Surgery Journal”

This study did not report conclusive results on whether a higher dose of platelets in platelet-rich plasma treatment impacts hair density, emphasizing the need for further evaluation of the trial details.

research Baseline trichoscopic values for afro‐textured hair in indigenous South Africans show lower density and unique features

January 2025 in “International Journal of Dermatology”

This study observed that indigenous South Africans with natural afro-textured hair have lower hair densities, varying shaft diameters, and distinct follicular unit patterns compared to other racial groups, with significant gender differences in some parameters, highlighting the need for tailored reference values in clinical settings.

4 upvotes 4 years ago

The user noticed hair regrowth after supplementing with vitamin D, magnesium, zinc, and vitamin B12, alongside using minoxidil for 3 years. They observed a lower hairline and improved density, supported by photographic evidence.

community Better density or just longer hair?

12 upvotes 1 week ago

The conversation discusses using dutasteride every other day for hair loss, with suggestions to increase the dose and add minoxidil for better results. Users recommend more frequent dosing to prevent further hair loss and achieve regrowth.

community Don’t like the density at all, 2nd hair transplant

in Transplants 160 upvotes 8 months ago

The user is unhappy with the results of their second hair transplant, feeling that grafts were wasted on an already transplanted hairline instead of increasing mid-scalp density. They regret stopping medications like Dutasteride, Minoxidil, and RU58841, which led to significant hair loss, and plan to restart them.

community Dutasteride likely reduces Bone Mineral Density

in Research/Science 5 months ago

Dutasteride may reduce bone mineral density, but there's no increased risk of osteoporosis or fractures compared to finasteride. Users suggest resistance training to counter potential bone effects.

How many grafts do I need for a receding hairline in a hair transplant? You typically need 800 to 2,500 grafts for a receding hairline.

learn Cetirizine

How does cetirizine reduce inflammation linked to hair loss? Cetirizine is proposed to lower prostaglandin D2 and raise prostaglandin E2 around hair follicles; three small trials of a compounded 1% topical report modest increases in hair density and shaft thickness, with minoxidil doing better head-to-head. Topical cetirizine is off-label and unapproved for hair loss, and the evidence is too thin to call it effective or safe.

learn Metformin

Does metformin help control DHT levels that trigger androgenic alopecia? Metformin has been shown to lower circulating androgens in women with PCOS, but no published study has measured scalp DHT, 5-alpha reductase activity in the follicle, or hair density in anyone taking it — so its effect on pattern hair loss is untested, and it is not a DHT blocker.
