Skin cells found at root of balding, gray hair



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.

New hair growth mechanism discovered



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.

Retailers charging women more than men for common hair loss medication



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 same drug strength and inactive ingredients.

Inherited, rare skin disease informs treatment of common hair disorders, study finds



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.

Study sheds light on regulation of hair growth across the entire body



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 patches form – and enable distinct hair densities in different body areas.

New way to activate stem cells to make hair grow



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.

Male-pattern baldness and premature graying associated with risk of early heart disease



Male-pattern baldness and premature greying are associated with a more than fivefold risk of heart disease before the age of 40 years, according to new research. Obesity was associated with a fourfold risk of early heart disease.

Practical hair regeneration technology



Researchers have developed a method for the mass preparation of cellular aggregates, also known as ‘hair follicle germs (HFGs)’, that may lead to a new treatment for hair loss.
