The skin systems of jawed vertebrates evolved diverse appendages like hair and scales from a common structure over 420 million years ago.

Hard skin features like scales, feathers, and hair evolved through specific protein changes in different animal groups.

Mice without certain skin enzymes have faster hair growth and bigger eye glands.

Hair restoration surgery can effectively increase pubic hair density, with patient satisfaction and natural results largely depending on the chosen hair pattern and graft design.

Fully regenerating human hair follicles not yet achieved.

The document suggests that blocking sweat glands with antiperspirants might allow skin-generated hormones to be absorbed, possibly increasing breast and prostate cancer risk.

Certain cells in the adult mouse ear come from cranial neural crest cells, but muscle and hair cells do not.

The document concludes that the technique allows for the detection of LDH activity in various tissues, showing where cells are actively metabolizing glucose.

Wild African goats have genetic adaptations for surviving harsh desert conditions.

Mitochondrial problems in tooth cells lead to bad enamel and dentin development in mice.

5α-reductase is essential for male sexual development and its inhibitors have potential in treating various conditions related to hormone action.

Dynamic, light touch is sensed through a common mechanism involving Piezo2 channels in sensory axons.

Odontogenic keratocysts are caused by abnormal Hedgehog signaling and can lead to tooth and bone issues.

Higher hair levels of zinc and chromium were linked to less cognitive decline in very old people.

Beard and moustache reconstruction can improve facial hair appearance with few side effects.

Using hair grafts from outside the safe zone requires careful placement to improve their survival and effectiveness.

Dense-packing follicular unit extraction is a safe and effective way to treat extensive scarring alopecia.

Beard hair transplantation is generally satisfying, requires 250-800 grafts, uses FUE to avoid scars, needs careful planning, has some risks, and hair regrowth starts after 4-6 months.

Hair transplantation effectively corrects hairline issues after midface-lifting surgery with high patient and physician satisfaction.

Using implanters in hair transplants can improve outcomes and cause less damage to hair follicles.

Only about 14% of hair follicles can be safely removed in hair transplants without affecting the surrounding area.

Eyebrow hair transplants have high patient satisfaction and require surgeons to have artistic and technical skills.

Hair loss surgeries like grafts, scalp reductions, and flap rotations can be effective for black men with proper technique adjustments.

The document suggests that for better patient satisfaction in hair transplants, high-quality photos are needed, and using a narrow donor strip might lead to fewer grafts and dissatisfaction, but filling the scar with FUE grafts and using tranexamic acid can improve results.

A man with baldness had successful hair growth after transplanting body hair to his head.

Follicular Unit Extraction (FUE) hair transplant is less invasive, leaves no scars, and has quicker recovery times, but it's more time-consuming and challenging. Automation helps speed up the process and improve graft survival, reducing the need for traditional strip surgery.

FUE is a modern hair transplant method that avoids large scars and is good for short hair.
