Isotretinoin may cause hair loss by increasing DHT through a precursor androgen, DHEAS. Treatments like topical antiandrogens (RU58841, pyrilutamide) and drugs increasing PPAR-y expression (pioglitazone) might prevent this hair loss.

Iron supplements can help improve hair thinning and brittle skin, but recovery time varies based on individual factors like ferritin levels and absorption rates. Regular blood tests are recommended to monitor ferritin and iron levels.

The user experienced hair improvement using a topical finasteride, minoxidil, and tretinoin combo, along with supplements like zinc, copper, magnesium, vitamin D3, K2, iodine, and boron. They believe these changes are due to addressing mineral deficiencies and possibly thyroid issues, despite skepticism from others.

User is experiencing hair thinning and sebum overproduction after starting finasteride and a hair growth supplement containing biotin, iron, zinc, and calcium. They suspect the finasteride might be fake but have noticed a side effect of watery semen.

CRISPR treatments for blood disorders have been approved, leading to discussions about its potential for treating hair loss (AGA). A study showed that editing a gene related to DHT sensitivity could lead to hair regrowth, suggesting CRISPR may eventually be used for AGA, but it's expected to be expensive and not soon available.

A user noticed increased hair loss after taking B12 supplements for two months, with B12 levels rising to 1500. They are seeking help as other tests show normal levels of minerals and vitamins.

The conversation discusses hair loss and bloodwork results, focusing on zinc, vitamin D, and ferritin levels. The user is experiencing telogen effluvium after surgery and seeks advice on supplementation.

A 20-year-old is experiencing hair thinning due to vitamin D deficiency and has completed a vitamin D prescription without seeing improvement. Suggestions include waiting a few months for potential regrowth or considering treatments like minoxidil or finasteride for androgenetic alopecia.

Low testosterone and estradiol may contribute to hair loss, and blocking DHT without sufficient hormone levels might hinder regrowth. The discussion highlights the importance of hormone balance, with some considering supplements and lifestyle changes to support hair health.

The conversation discusses hair loss treatments, focusing on iron supplements for low ferritin levels and considering finasteride and minoxidil if thinning persists. There is debate over starting with finasteride versus dutasteride, with some users advocating for dutasteride due to its potency, while others caution about potential side effects.

The user has been microneedling at 0.25mm once a week for 4 weeks and noticed further hairline recession. They are concerned about the impact of vitamin deficiencies, like biotin, on hair growth.

The user has been using finasteride and minoxidil for 11 months but is experiencing increased hair loss and no signs of improvement. Another user shares a similar experience and mentions iron deficiency and thyroid issues affecting hair loss despite using the treatments.

Microneedling is effective for hair growth, especially when combined with finasteride and minoxidil, but concerns exist about potential long-term skin damage. Users report increased collagen and elastin deposition, but the long-term effects on the scalp remain uncertain.

The user noticed hair thinning since age 15, initially attributed to a Vitamin D deficiency. They are currently using Rogaine and considering Propecia but are hesitant about a scalp biopsy; they seek financially practical treatments for male-pattern baldness.

The conversation is about the role of vitamin deficiencies in hair loss and the effectiveness of treatments like Minoxidil, finasteride, and RU58841. It concludes that while vitamins and nutrition are important, they are not the primary solution for androgenic alopecia.

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

Before starting hair loss treatment, it's suggested to undergo various blood and health tests to minimize side effects. The checklist includes tests for kidney function, liver enzymes, blood sugar, vitamins, hormones, and more.

Eli Lilly's drug baricitinib showed effectiveness in treating alopecia areata, with higher doses resulting in significant hair regrowth compared to placebo. The treatment is not for male pattern baldness.

The user experienced increased hair shedding after taking a multivitamin containing selenium and questioned if selenium was the cause. The conversation revolves around the potential negative effects of selenium on hair health.

A user experiencing significant hair loss while on finasteride and minoxidil found out they had vitamin D and iron deficiencies. After adding iron, vitamin D, and a multivitamin with zinc to their treatment, they saw reduced hair fall within a week.

Hair loss affects confidence, with discussions on treatments like finasteride, minoxidil, and RU58841. Emphasis is placed on self-acceptance and building confidence beyond appearance.

The conversation discusses the use of microneedling for hair loss, with concerns about potential long-term effects like fibrosis and scarring. Users share experiences and opinions on combining microneedling with treatments like minoxidil and finasteride, but there is uncertainty about the long-term safety and efficacy.

The conversation discusses scalp itching and tenderness after microneedling, despite using medicated shampoos and proper sanitation. The user plans to see a dermatologist and is concerned about possible infection or allergic reaction.

The post discusses potential links between low vitamin D levels and hair loss, and how correcting this might impact the effectiveness of Minoxidil and Finasteride treatments. The responses vary, with some suggesting that vitamin D deficiency would cause overall scalp hair loss, while others believe it would first affect the most sensitive areas.

Hair loss discussion mentions treatments like Finasteride, Dutasteride, and Minoxidil. Users share experiences, side effects, and advice on using these treatments.

Dutasteride may affect testosterone levels, leading to high ferritin and iron levels, which can cause hair loss. High ferritin might be linked to past heavy drinking or hemochromatosis.

Excess Vitamin A and topical retinoids can cause diffuse hair shedding. The user suspects their chronic telogen effluvium may be linked to using adapalene, a topical retinoid.

Trans woman experiences hair thinning despite low testosterone and treatments like finasteride and microneedling. Possible causes discussed include past eating disorder and current stack of medications and supplements.

Iron supplementation may be more effective than Minoxidil for hair loss. Checking ferritin levels is important, as both low and high levels can affect health.

A user noticed non-itchy, non-bleeding spots on their scalp while experiencing hair loss. Replies suggest the spots are likely sunspots or liver spots and recommend seeing a dermatologist; hair loss is attributed to male pattern baldness.
