Red laser therapy helped regrow hair in an alopecia areata patient within 21 days.

Androgenetic alopecia, a genetic disorder affecting up to 50% of adults, is caused by an excessive response to androgens leading to hair follicle shrinkage. Treatments include FDA-approved drugs, other therapies like low-dose oral minoxidil, and hair transplantation.

Improved methods create smaller, more effective gelatin nanoparticles for skin delivery, and new caffeine nanocrystals enhance absorption and effectiveness.

Nanocrystals improve skin penetration and stability of caffeine, suggesting a new method for delivering similar substances through the skin.

The laser scanner device was more effective at increasing hair density than the laser hat in treating androgenic alopecia.

Red light at 627 nm can safely trigger IL-4 release in skin cells, potentially helping treat inflammatory skin conditions.

Low-level laser therapy helps increase hair growth in female pattern hair loss but not in telogen effluvium.

ICG-enhanced NIR laser therapy may be a promising acne treatment with improvement and no side effects.

The new particle system could be a promising treatment for diseases related to the 5-α reductase enzyme.

Blue laser light reduces energy in mouse skin cells and creates harmful oxygen compounds, possibly harming the cells.

Blue light therapy is safe for skin and may protect against UV radiation.

A new hand-held light therapy device was found to be safe and effective for treating mild-to-moderate acne.

Plants change their growth in response to shade based on light signals detected by phytochrome.

Low-level laser therapy effectively reduces the size of pressure ulcers compared to placebo.

PRP and LLLT can improve hair growth in AGA, but more research needed.

UV radiation can help sterilize wounds and promote healing but requires careful use to avoid damaging cells.

Low-level laser therapy significantly increases hair density in adults with hair loss, with low-frequency treatment being more effective.

At-home laser and light skin devices are less effective than professional ones, with limited scientific evaluation, but some show promise for wrinkles, hair growth, and acne.

Low-level laser therapy can stimulate hair growth more effectively than fake devices, but patient satisfaction is similar for both. Results should be taken with caution due to small study sizes and differences between studies. More research is needed.

At-home laser and light devices can safely reduce acne and hair growth when used correctly but are less effective than professional treatments.

Near-infrared laser therapy with Indocyanine Green dye improves acne by reducing inflammation without side effects.

Low-level laser therapy may help with hair regrowth in alopecia areata but its effectiveness for psoriasis and atopic dermatitis needs more research.

Human hair growth involves active, resting, and intermediate phases, and examining plucked hairs can teach students about hair biology and diseases.

Minoxidil, finasteride, and low-level laser light therapy effectively treat hair loss.

The silk fibroin-based hydrogel shows promise for treating melanoma and healing infected wounds by killing tumor cells and bacteria, and supporting skin recovery.

Caffeine nanocrystals for skin products stay stable with the right stabilizer, but grow in size at higher temperatures.

Photodynamic Therapy is an effective treatment for mild to severe acne.

Researchers created early-stage hair-like structures from skin cells, showing how these cells can self-organize, but more is needed for complete hair growth.

Coating surfaces with human hair keratin improves the growth and consistency of important stem cells for medical use.

New physical methods like electrical currents, ultrasound, and microneedles show promise for improving drug delivery through the skin.
