Researchers have discovered a new way to activate the stem cells in the hair follicle to make hair grow. The research may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss associated with such factors as hormonal imbalance, stress, aging or chemotherapy treatment.
To paraphrase the classic poem, no hair is an island entire of itself. Instead, scientists have discovered that all hairs can communicate with each other and grow in coordination across the entire body. This is regulated by a single molecular mechanism that adjusts by skin region to ensure efficient hair growth - so no bald […]
Researchers studying an inherited disorder of skin, hair follicles, nails, sweat glands, and teeth called hypohidrotic ectodermal dysplasia (HED) have identified a mechanism that may also be disrupted in male pattern baldness, a more common condition.
Women pay an average of 40 percent more than men for minoxidil foams - a hair loss remedy most commonly known as Rogaine - according to a new analysis. The price difference appears despite the fact that the men's and women's version of the products - which are branded and marketed differently -- contain the […]
Regulatory T cells (Tregs; pronounced 'tee-regs'), a type of immune cell generally associated with controlling inflammation, directly trigger stem cells in the skin to promote healthy hair growth, researchers have discovered. Without these immune cells as partners, the researchers found, the stem cells cannot regenerate hair follicles, leading to baldness.
Researchers have identified the cells that directly give rise to hair as well as the mechanism that causes hair to turn gray – findings that could one day help identify possible treatments for balding and hair graying.
Short men may have an increased risk of becoming bald prematurely. An international genetic study at least points in this direction. During the study, the scientists investigated the genetic material of more than 20,000 men. Their data show that premature hair loss is linked to a range of various physical characteristics and illnesses.
Alopecia areata, atopic dermatitis and vitiligo are highly visible dermatologic conditions that can have a negative effect on patients’ quality of life and overall health. An emerging treatment option, however, could provide effective therapy.
Coloring hair has become a common practice, particularly for people who want to hide their graying locks. But an ingredient in many of today's commercial hair dyes has been linked to allergic reactions and skin irritation. Now scientists have developed a potentially safer alternative by mimicking the hair's natural color molecule: melanin.
