Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.

Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.

A boy's hair grew back after he stopped using orthodontic headgear that caused temporary hair loss.

The simulation showed that hypobaric pressure improves drug delivery through the skin, but stretching alone doesn't fully explain the increase.

Fat tissue-derived cells show promise for repairing body tissues, but more research and regulation are needed for safe use.

Women with PCOS often have skin problems like excessive hair, acne, hair loss, and dark patches, which can be treated with hormonal and non-hormonal therapies.

Skin problems are common and important signs of eating disorders and treating the eating disorder can improve these skin conditions.

Abnormal scalp whorls can indicate brain development issues but may also be seen in neurologically normal people.

Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.

Keratin-based particles safely improve hair strength, smoothness, and heat protection.

Best hair transplant results happen when tissues are least damaged.

Environmental and cosmetic factors, including heat, chemicals, and sun exposure, can cause hair loss and damage.

Concrete made from animal bones and human hair is stronger and more environmentally friendly than traditional concrete.

The study concluded that a protein important for hair strength is regulated by certain molecular processes and is affected by growth phases.

Calcium microcapsules are better for long-term use in artificial dermal papilla, while barium microcapsules are good for short-term.
