Older people's sweat glands are less effective at helping skin wounds heal due to weaker cell connections.

Scientists have created a method to deliver specific cells that can regenerate hair follicles, potentially offering a new treatment for hair loss.

Increasing Wnt5a in mice skin delays hair growth but doesn't stop it.

Two siblings were the first reported cases of inheriting both eye coloboma and loose anagen syndrome together.

Inflammation plays a key role in activating skin stem cells for hair growth and wound healing, but more research is needed to understand how it directs cell behavior.

Early diagnosis and aggressive treatment are key for managing rare scalp disorders that cause permanent hair loss.

Lupus can cause hair loss and nail changes, with treatments available for both.

COVID-19 may harm male fertility and damage the reproductive system.

Bioactive molecules show promise for improving skin repair and regeneration by overcoming current challenges with further research.

Non-invasive methods show promise for diagnosing skin diseases like psoriasis and lupus but need more research for regular use.

Researchers found that dissecting folliculitis of the scalp is linked to obesity, severity increases with duration and number of nodules, and early treatment is important to prevent scarring.

The new method for isolating stem cells from fat is simple and effective, producing cells that grow faster and are better for hair regeneration.

The conclusion is that accurate diagnosis of different types of hair loss requires careful examination of tissue samples and understanding of clinical symptoms.

Hair in mammals likely evolved from glandular structures, not scales.

Flightless I protein affects hair growth, with low levels delaying it and high levels increasing hair length in rodents.

New markers and pathways have been found in skin tumors, helping better understand and diagnose them.
