Microneedling the scalp can cause sneezing, runny nose, and watery eyes due to nerve stimulation, histamine release, reflex actions, or sinus relief. Several users experience similar symptoms.

OP injured their temple using derma rolling and tretinoin, causing peeling and potential hair follicle damage. Users suggest the injury might be permanent, possibly resulting in scar tissue where hair won't grow.

Microneedling can cause sneezing and eye tearing due to nerve stimulation, particularly near the temples and forehead. Some users find it lessens over time, while others prefer using finasteride and minoxidil for hair growth.

A 12-year-old diagnosed with alopecia shares their experience and current treatments, including Dermovate, an unnamed cream, and liquid iron. The community offers support and encouragement.

This post and conversation are about the molecular mechanisms triggered by microneedling, specifically its effects on inflammation, tissue remodeling, epithelial proliferation, differentiation, and collagen synthesis. The discussion highlights the potential benefits of microneedling for hair loss treatment.

The user is experiencing irritation from using PG with RU58841 and is seeking alternative solutions like K&B in the UK. They report redness, itchiness, and flaky skin from the current treatment.

The conversation discusses potential causes of pigmentation around hair follicles, suggesting sebum buildup, autoimmune conditions, or dermatitis. Treatments mentioned include finasteride, dutasteride, and an anti-inflammatory diet, with a recommendation to consult a doctor for a proper diagnosis.

A user with diffuse hair loss for a decade tried various treatments, including LLLT Helmet, supplements, topicals, and hair transplants. They found relief from scalp inflammation and itching using a topical solution made from crushed Xeljanz pills mixed with ethyl alcohol.

Vitamin E and K deficiencies due to exocrine pancreatic insufficiency may affect hair growth. A scalp biopsy is recommended to check for autoimmune-related hair loss.

User experienced scarring from microneedling at fast speed and paused treatment for 3-4 weeks to recover. Advice given includes waiting a full month for recovery to avoid scars.

The conversation discusses concerns about the potential risk of cancer from creating new hair follicles through microneedling, due to stem cell division. Specific treatments mentioned include microneedling, caffeine-containing anti-hair loss shampoos, and other unspecified topicals.

RU58841 helped reduce scalp itching for some users within a week, while others experienced immediate relief. Some users reported initial irritation from the solution, possibly due to the carrier used.

The conversation discusses using tretinoin for hair loss and whether applying SPF on the scalp is necessary if hair covers the treated areas. The user is considering this treatment despite having no completely bald patches.

A user found that scalp itch might be linked to inflammation rather than DHT alone and noticed hair improvement with certain cancer drugs. They also discovered that black seed oil relieved their scalp itch and are experimenting with a mix of essential oils for dry scalp, questioning if oils affect minoxidil absorption.

The conversation is about making a topical solution from clascoterone powder, with references to using a RU58841 mixing guide for guidance. Concerns about product authenticity and bulk purchase requirements are also discussed.

Microneedling can cause skin shedding and inflammation, with some users adjusting needle size or frequency to reduce these effects. Some users combine microneedling with treatments like minoxidil, while others prefer smaller needles or alternative treatments like dutasteride.

OP developed hives after using Kx 826 (Pyrilutamide) 1% twice daily for 3 weeks. The hives appeared on the arms, chest, and groin area.

A user experienced severe scalp itching with MPB and found Nizoral ineffective. A doctor diagnosed seborrheic eczema and prescribed Betacap, which relieved the itching.

Seborrheic dermatitis can cause hair loss, and treatments like ketoconazole shampoo, topical steroids, and oral antifungals may help. Some consider using finasteride and minoxidil for hair loss despite dermatitis.

The conversation discusses using minoxidil and finasteride for hair loss, with concerns about absorption and considering adding tretinoin for better results. Microneedling is suggested as a method to improve absorption, with varying depths and frequencies recommended.

Dermatologists often advise against at-home microneedling due to risks of scarring, infection, and improper technique. Professional guidance is recommended for safe and effective use, with some users reporting positive results when done correctly.

Topical dutasteride may have limited absorption due to its higher molecular mass compared to finasteride, potentially affecting its efficacy in suppressing DHT locally. Microneedling might enhance dutasteride absorption, possibly offering stronger local DHT suppression with fewer systemic effects.

Tretinoin and microneedling both enhance hair growth through different mechanisms, with microneedling being considered safe for long-term use. Optimal microneedling needle length varies, but 0.8 mm is suggested for hair growth, and a Dermastamp is recommended to avoid skin damage.

Microneedling can cause infections if not done carefully; users suggest using alcohol swabs and reducing needle depth to avoid issues. Proper sanitation and gentle pressure are key to preventing bleeding and infection.

The "DHT itch" is real and likely due to inflammation at the hair follicle, exacerbated by increased testosterone or androgens. Treatments mentioned include dutasteride, minoxidil, finasteride, and various topical solutions.

Apply tretinoin at night and minimize sun exposure. Use sunscreen as a last resort due to its messiness and need for frequent reapplication.

Topical Calcipotriol (vitamin D derivative) may help with hair regrowth, especially for alopecia areata. The user wonders if adding classic vitamin D to lotions like Minoxidil could have a similar effect.

The user experienced red pimples and a rash from using topical minoxidil, possibly due to propylene glycol. Suggestions included seeing a dermatologist, switching to foam without propylene glycol, using Nizoral, and adjusting application timing.

The conversation is about using a DIY topical Cetirizine 1% solution with microneedling for hair loss treatment. Concerns were raised about potential side effects and the effectiveness of Cetirizine for this purpose.

The user has been using dutasteride, lymecycline, betamethasone, and minoxidil for hair loss but struggles with eczema and dry skin. They feel hopeless as no treatments or moisturizers have helped, and they are concerned about their appearance due to their soft facial features.
