Various techniques and tools for hair restoration were presented in 1998, including a mathematical model for donor area, use of lasers in surgery, methods for controlling grafted hair direction, and ways to increase graft yield. Satisfaction rates were around 39%, and studies showed trauma and dehydration can damage hair follicles.

Melanocyte transplantation can safely restore skin color, especially in stable vitiligo, but must be chosen carefully based on the disease phase.

Aging changes scalp cells, possibly affecting hair health in older women.

Thioredoxin reductase 1 does not affect glucocorticoid receptor activity in hair follicle cells.

Infrared spectral imaging can effectively study protein distribution in hair follicles during hair growth.

Stem cells can improve skin grafts by enhancing blood flow and hair growth.

Collagen peptides from marine and bovine sources may help prevent hair loss by affecting hair follicle stem cells differently.

Ruxolitinib helps protect skin stem cells and keeps skin healthy in mice with skin GVHD.

Hair transplants can lead to hair loss from lichen planopilaris, and patients should be tested and wait two years before the procedure.

Both pretrimmed and direct nonshaven methods are effective for hair transplants; pretrimmed takes longer but yields denser, longer hair.

The dressing generates hydrogen sulfide to help heal wounds faster by reducing inflammation and promoting cell growth.

The new hair transplant technique is fast, effective, and satisfying for patients with different hair types.

Androgenetic alopecia involves immune cell disruptions, especially increased CD4+ T cells around hair follicles.

Artificial hair implants can quickly improve looks and life quality, but they have risks like infection and early fiber loss, so more research is needed to confirm their safety and effectiveness.

Using microscopes in hair transplants reduces follicle damage.

Early attempts at using cloned cells for hair transplants failed, but 3D cell growth showed some promise.

Hair restoration surgery can worsen psoriasis, so careful planning is needed.

All types of Platelet-Rich Plasma (PRP) can treat hair loss, but homologous PRP works best due to its higher platelet count and growth factors from multiple donors.

Using healthy donor stem cells can potentially calm overactive immune cells and reduce inflammation in severe hair loss patients, offering a possible treatment method.

Different markers are found in stem cells of the scalp's hair follicle bulge and the surrounding skin.

Identifying specific hair follicle parts could lead to better hair loss treatments.

PRP and stem cells can help treat baldness by promoting hair growth.

Alopecia areata can be triggered by specific immune cells without genetic or environmental factors.

Fat under the skin releases HGF which helps hair grow and gain color.

Scalp micropigmentation is a successful, non-surgical way to make hair look fuller.

Estetrol (E4) may help treat female pattern hair loss by prolonging hair growth.

Aging changes female scalp cells, likely affecting hair health.

The products significantly promote hair growth and maintain hair bulb health.

The conclusion is that the new method makes collecting cells from plucked hair to create stem cells more efficient and less invasive.

Poor blood supply in hair follicles is linked to nutrient deficiency in patients with female pattern hair loss, and adding more nutrients could potentially fix this.
