Microneedling can cause a sneezing reflex due to tingling in the nose. Users report this reaction, especially in the temple region.

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.

The "crunching" sound during microneedling is likely the needles penetrating the scalp's outer layers, not cutting hair. Users suggest using a derma stamp instead of a roller to avoid potential hair damage.

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.

Iontophoresis and sonophoresis can enhance drug delivery into the scalp. Combining these methods may improve the effectiveness of topical treatments like dutasteride and certain peptides.

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 experienced microinflammation on the crown after using mometasone furoate (Nasonex) nasal spray. They are seeking information on the relationship between this corticosteroid and hair loss.

Fatty acid metabolic signaling can activate epithelial stem cells for hair regeneration. Oleic and palmitoleic acids showed the best results, but practical application on humans remains uncertain.

Hair growth relies on mechanical forces, not just chemicals, with tissue acting like a motor. Minoxidil and finasteride help, but maintaining tissue elasticity and addressing mechanical issues are essential.

Microneedling combined with latanoprost may convert vellus hairs to transitional or terminal hairs. The user suggests using oral minoxidil to increase vellus hair, then applying a high concentration of latanoprost with microneedling for conversion.

A user experienced burning, itching, and soreness on their scalp after a perm in 2021, despite using oral finasteride, oral minoxidil, and ketoconazole shampoo. They are seeking advice on whether to pursue further medical tests or consult a neurologist for nerve pain.

Exploring different treatments for hair loss, such as cosmeRNA and HMI-115 which are small interference messenger RNA that inhibits the DHT receptor and an antibody that binds to the prolactin (PRL) receptor respectively; and researching mechanism and environment of hyperresponders.

Microneedling may enhance hair regrowth by transferring stem cells to dormant follicles, improving the effects of minoxidil. Users discuss using microneedling with needle lengths around 1.5mm to stimulate hair growth.

Low oxytocin levels in hair are linked to reduced empathy and may affect hair growth. Cinnamic acid can promote hair growth by activating oxytocin receptors.

There are no tests to determine genetic follicle sensitivity for hair loss, and conclusions are based on hypothetical or post-balding observations. Finasteride is mentioned as an easy, consistent treatment option compared to natural treatments.

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.

Osteopontin, a protein involved in hair growth on moles, may help with hair loss. However, it is also linked to Alzheimer's, cancer, and bone development, so caution is advised.

A user discusses their experience with at-home microneedling at 1mm for hair growth, feeling like they're hitting their skull. Other users suggest lowering the needle depth or stopping due to discomfort.

Transplanting mice skin to humans is not feasible due to immune rejection, but some suggest genetic modification or immune suppression could make it possible. Xenograft hair transplants are discouraged.

Male pattern baldness (MPB) may be influenced by androgen receptors in scalp hair follicles and potentially poor blood flow. Transplanted hair is not immune to DHT, and factors like inflammation and scalp tension might also contribute to hair loss.

MCL-1 protein may help maintain hair follicles in the growth phase and prevent miniaturization. There is interest in experimental treatments like exosomes, peptides, or stem cell serums to upregulate MCL-1 for hair loss, especially for those not using minoxidil or finasteride.

A user describes using a Dermastamp for microneedling their scalp, noting a crunching sound when pressing it firmly. Another user suggests the crunching might be from breaking up scalp calcification.

A new "third cell" discovery in Japan could be key to fully regenerating hair follicles, with human trials possibly starting in 2027-2028. AI is expected to accelerate medical discoveries, potentially leading to a hair loss cure within a few years.

The conversation discusses hair loss linked to BDNF-increasing nootropics like Semax and Lions Mane. Suggested topical treatments include capsaicin, beta-glucan, and ginseng to counteract TGF-B activation.

The conversation is about finding a pure high molecular weight hyaluronic acid for the scalp after microneedling. A user suggests using a product from The Ordinary.

A person is experimenting with microneedling on one temple while using Minoxidil to address hair loss. They plan to needle weekly and apply Minoxidil twice daily, avoiding application around needling sessions.

Hair loss itch is caused by DHT attacking follicles and stimulating nerves. Finasteride users who respond well don't experience this itch.

Oleic acid and microneedling are being explored for hair regrowth, but results are mixed. Addressing DHT and fibrosis is crucial, with treatments like finasteride, minoxidil, and scalp massage also discussed.

The conversation discusses the potential of cinnamic acid for hair growth. It also mentions treatments like Minoxidil, finasteride, and RU58841.

Concerns about metal particles from dermapen or dermaroller needles potentially entering the skin and lymph nodes, similar to tattoo needles. Discussion includes the possibility of using Minoxidil, finasteride, and RU58841 for hair loss treatment.
