Videomicroscopic images were taken at baseline, 3 months, and 6 months, and analyzed for changes in vellus hair counts, terminal hair counts, and shaft diameter. Both videomicroscopic and global images underwent blinded review for evidence of subjective improvement. Patients also answered questionnaires assessing hair growth throughout the study Lam Institute for Hair Restoration - Propecia (Finasteride) Tutorial 2: From Vellus to Terminal Hairs
Mean increased hair diameter of 11.9 µm in finasteride+MNX group & 7 µm in MNX group at 6 months Mean increased hair density of 24.7 hairs/cm 2 in finasteride+MNX group & 21.9 hairs/cm 2 in MNX group at 6 months Approximately 93% of patients had improved GPA in both groups Decreased serum DHT level in finasteride+MNX group: Folliculiti In other words, hair loss is seen as a process of hairs shrinking from healthy terminal hairs that progressively miniaturize to fine, vellus hairs.The mechanism by which finasteride works is through blocking the conversion of testosterone to dihydrotestosterone (DHT) via an enzyme 5-alpha-reductase Type 2 The growth of vellus follicles to terminal size (thick, strong, pigmented hairs that have fully matured) was 12% with Finasteride. The growth of vellus follicles to terminal size was 26% with 5% strength RU58841. The 0.5% strength RU58841 solution induced almost no effect. Expectedly, the Finasteride placebo induced no effect
Therapeutic Efficacy of Finasteride in Female Pattern Hair Loss. Finasteride has been commonly used in men with AGA and benign prostatic hyperplasia, and is progressively prescribed in women with hyperandrogenism-associated conditions including acne vulgaris, hirsutism and pattern alopecia induced by testosterone in female-to-male transgender.

When oral finasteride was combined with topical anti-androgens and minoxidil, a significant (P < 0.0001) mean increase in THD(+37) was associated with a significant (P < 0.05) mean decrease (−3%) in the vellus hair percentage, implying that the observed increase in THD might have arisen from the conversion of vellus hairs to terminal hairs. Shrinking follicles also cause the hair shaft to become thinner after every cycle, eventually leading to soft, light hairs known as vellus hairs.1 How Does the DHT Blocker Finasteride Work? Finasteride is one of the few FDA-approved medications for preventing hair loss and promoting hair growth

These fine hairs are known as 'vellus hairs'. A hormone by-product called DHT causes the tiny vellus hairs on the arms, legs, faces and other areas to grow thicker and darker during puberty. The same DHT has the reverse effect on the hairs on the head, later in life Vellus hairs are produced as a result of follicle miniaturization, where the follicle slowly gets smaller and smaller until it produces tiny vellus hairs. Anti-androgen drugs like finasteride are one of the first-line treatments of AGA and excess DHT. These directly target elevated DHT levels How many hairs have you already lost? If you have already clear bald spots on your scalp (or spots with vellus hair - 2 mm long hair), derma roller won´t help you regrow any new hair in these areas.

The normal ratio of terminal hairs to vellus hairs on the male head is 6-8 terminal hairs to 1 vellus hair. In balding men, the ratio is anywhere from 0.1 to 3.9 terminal hairs to 1 vellus hair. Male patients on finasteride 1mg improved from a starting ratio of 1 terminal hair to 1.7 vellus hairs to 1 terminal hair to 1.1. Aside from that, the vellus follicles, or thin hairs that are barely noticeable, have also displayed substantial terminal growth. So it goes to show that both Ru58841 and Finasteride are both effective in treating the issue of hair loss. But what's amazing is that the results of the test also showed that anagen follicles have grown at least.

How Finasteride Affects PCOS Symptoms. Finasteride works by blocking androgens, which are a group of hormones that play a role in male traits and reproductive activity. When androgens in the hair follicles are blocked, PCOS-related hair loss and hirsutism lessen. 70-80% of women with excess androgens demonstrate hirsutism The growth of vellus follicles to terminal size (thick, strong, pigmented hairs that have fully matured) was 12% with Finasteride. The growth of vellus follicles to terminal size was 26% with 5% strength RU58841. The 0.5% strength RU58841 solution induced almost no effect. Expectedly, the Finasteride placebo induced no effect When estrogen predominates, a woman's face typically has vellus hair -fine, short and almost invisible like 'peach fuzz'.

Background The relationship between female pattern hair loss (FPHL) and androgenic hormones is not well established, but some evidence indicates oral finasteride may be efficacious in FPHL. Use of a topical formulation has been proposed to minimize unwanted effects. Objectives Our objective was to compare the efficacy and safety of topical 0.25% finasteride combined with 3% minoxidil solution.
In normal non-balding men, the ratio of terminal hairs to vellus hairs male head is 6-8 terminal hairs to 1 vellus hair, but in balding men, the ratio ranges between 0.1 to 3.9 terminal hairs to 1 vellus hair. Balding persons on Propecia changed from a starting ratio of 1 terminal hair to 1.7 vellus hairs to final ratio of 1 terminal hair to 1. Compared to the placebo group, the Viviscal group had 57% more terminal hairs, a 10% larger hair diameter, and 9% fewer vellus hairs. At 180 days, compared to baseline, patients on Viviscal showed an almost 80% increase in terminal hairs, a hair diameter increase of 11.67%, and a 14% increase in vellus hairs Finasteride is taken orally once per day and is clinically tested to be an effective treatment for slowing down or arresting hair loss for most men. Male pattern baldness is the cause of most hair loss experienced by the male population and is caused by the effects of the male hormone dihydrotestosterone (DHT) on genetically susceptible hair. Minoxidil topical lotion work on active hair follicles still capable of producing hair. For those with pattern hair loss, minoxidil can reduce and reverse the rate of hair follicle miniaturization, and can reverse the transformation of terminal follicles that produce full-size hairs from vellus follicles that only grow peach fuzz
Whiting did serial 4-mm scalp punch biopsies on man and women undergoing blinded treatment with either finasteride or placebo. Among the men being treated with finasteride, he found a mean increase in terminal hairs of 5.4 per biopsy and a reduction in vellus hairs of 3.1 per 4-mm punch biopsy Vellus hairs are fine, lightly pigmented hairs that cover most of the body before puberty. Pubertal androgens promote the conversion of these vellus hairs to coarser, pigmented terminal hairs. The level and duration of exposure to androgens, the local 5-alpha-reductase activity, and the intrinsic sensitivity of the hair follicle to androgen.

The hairs eventually become so small that they resemble the fine, vellus hair normally present in small numbers on the scalp and body. Miniaturized hairs have little cosmetic value These hairs are known as vellus hair and the process is known as miniaturisation of hair follicles. Vellus hair is fine hair that grows on most parts of the body except the lips, palms of the hands and soles of the feet. The miniaturised hair follicles enter a permanent state of catagen or rest phase, instead of resting before a new growth phase Androgenetic alopecia is a genetically determined disorder and is progressive through the gradual conversion of terminal hairs into indeterminate hairs and finally to vellus hairs. Patients with androgenetic alopecia have a reduction in the terminal-to-vellus hair ratio, normally about 4:1. Following miniaturization of the follicles, fibrous.
Topical, over-the-counter products such as Minoxidil, more popularly known as Rogaine, cause the hair to grow for a longer period of time.
