Transplanted hair follicles show significant changes after FUE, needing more research.

Zolpidem shows up in hair from the top back of the head after one dose and fades over time, suggesting it gets into hair through blood and sweat.

Platelet-Rich Plasma (PRP) therapy can effectively treat various hair loss conditions, improve hair count, thickness, and density, and potentially speed up results when combined with surgical techniques.

Modern hair restoration techniques can effectively treat hair loss and provide natural-looking results.

Epithelial-mesenchymal interactions control hair growth cycles through specific molecular signals.

Hormone treatments in transsexual individuals reduce hair growth and oil production in male-to-females and increase them in female-to-males.

Oxidative stress contributes to hair graying and loss as we age.

The document concludes that understanding hair structure is key to diagnosing hair abnormalities and recommends gentle hair care for management.

Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.

The document concludes that electrolysis and thermolysis can permanently remove hair but calls for better regulation to ensure safety, and notes a possibility of hair regrowth and rare complications.

Hair restoration surgery has advanced, focusing on natural results and may improve further with new techniques and therapies.

Certain treatments can speed up local hair growth in mice but don't change the overall hair growth pattern.

PGA-4HGF may help treat hair loss by activating hair growth pathways and extending the hair growth phase.

Hair follicles and deer antlers regenerate similarly through stem cells and are influenced by hormones and growth factors.

Androgens play a key role in hair growth and disorders like baldness and excessive hairiness.

Phaeodactylum tricornutum extract helps hair follicle cells grow by activating the ERK1/2 pathway.

Hair analysis is better than urine and blood for detecting past drug use.

Involucrin helps strengthen the inner parts of human hair.

AGA causes hair loss by shrinking hair follicles due to DHT binding, and can be treated with finasteride and minoxidil.

Male hormones are important for hair and oil gland development and can cause conditions like excessive hair growth and acne.

FUE hair transplants have improved to give more natural results with less scarring and pain.

Most women with excess hair growth have an underlying hormonal issue, often treated with medication and hair removal methods.

Tight hairstyles and chemical relaxers can cause hair loss known as traction alopecia.

High levels of testosterone and 5α-DHT can lead to cell death in cells important for hair growth.

Higher IGF-1 levels in hair follicles link to better finasteride results for hair loss.

The document concludes that more research is needed to understand excessive hair growth in women with normal hormone levels and regular ovulation.

Follicular Unit Extraction is a less invasive hair transplant method with potential for natural results but has challenges like longer surgery time and higher cost.

Hirsutism in women often indicates a hormonal imbalance and can be managed with a combination of hormonal treatments and hair removal methods.

Hair loss in Androgenetic alopecia (AGA) is due to altered cell sensitivity to hormones, not increased hormone levels. Hair growth periods shorten over time, causing hair to become thinner and shorter. This is linked to miscommunication between cell pathways in hair follicles. There's also a change in gene expression related to blood vessels and cell growth in balding hair follicles. The exact molecular causes of AGA are still unclear.

Finasteride and minoxidil are effective, low-risk treatments for male hair loss, and patient education on these therapies is important.
