Did you mean Hair Follicle Count?

Glossary Hair Follicle Count

total number of hair follicles in a specific area

Hair Follicle Count refers to the total number of hair follicles present on the scalp or a specific area of the body. This metric is often used in medical and cosmetic evaluations to assess hair density, diagnose conditions like alopecia, and plan treatments such as hair transplants.

The Role of Hair Follicle Counts and Ratios in the Histopathological Assessment of Androgenic Alopecia, Alopecia Areata and Telogen Effluvium: Does Counting 'Count'?

research THE ROLE OF HAIR FOLLICLE COUNTS AND RATIOS IN THE HISTOPATHOLOGICAL ASSESSMENT OF ANDROGENIC ALOPECIA, ALOPECIA AREATA AND TELOGEN EFFLUVIUM: DOES COUNTING ‘COUNT’?

March 2023 in “Human Pathology”

This review found that while follicular hair counts and ratios assist in diagnosing non-scarring alopecia, they should be used alongside specific morphological features for accurate diagnosis.

community Haircafe slams pp405 presentation. Are results really that bad?

64 upvotes 5 months ago

PP405 shows promise in activating dormant hair follicles and increasing hair counts but lacks detailed efficacy data compared to minoxidil and finasteride. Opinions are mixed, with some optimism and skepticism about its effectiveness.

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 The mechanism of androgenic alopecia

36 upvotes 11 months ago

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

community Can microneedling damage existing hair?

in Microneedling 9 upvotes 1 year ago

Microneedling is unlikely to damage existing hair if done with a device using a smaller needle count, like a 9-needle cartridge, and a stamping motion. Hair follicles are deeper than the typical needle penetration depth.

community Minoxidil: How It Changes the Scalp Hormone Environment

78 upvotes 7 months ago

Minoxidil increases blood supply to the scalp, strengthening dormant follicles and extending the growth phase, but may increase scalp activity that can be countered with DHT blockers. Women experiencing side effects from finasteride or dutasteride for hair loss might consider alternatives like estrogen, especially if on birth control.

learn Hair Transplant

How many grafts do I need for a hair transplant? You typically need 1,000 to 7,000 grafts depending on hair loss extent and goals.

learn Finasteride

Does hair strand thickness decrease in men with androgenic alopecia? Can finasteride help restore it? Androgenic alopecia thins hair strands by miniaturizing follicles. The pivotal finasteride trials (1,553 men, 1 mg/day, two years) report increased hair counts and improved assessed appearance, but they measured density, not the diameter of individual strands, so the effect on thickness itself is not established.

learn Peppermint

Which is more effective: peppermint essential oil or extract in shampoo? Neither form has been tested for hair loss in people. Peppermint essential oil is the only one with any experimental support — a single four-week mouse study in which 3% peppermint oil outperformed 3% minoxidil on follicle counts — while peppermint extract in shampoo is a low-concentration cosmetic ingredient with no hair-growth data.
