From the Daily Mail: Scientists have uncovered a simple way to cure hair loss – and it only takes 20 days to take effect.
Researchers at National Taiwan University created a promising rub–on serum that restores hair growth in mice.
In their lab experiments, the serum stimulated fat cells in the skin that regenerated hair follicles.
According to the experts, the serum contains naturally derived fatty acids that don’t irritate the skin.
And it could soon be available for people in the form of an over–the–counter skincare product.
According to a report this week by NewScientist:
Skin irritation promotes hair growth on mice by stimulating their fat cells – and a serum could bring about the same effects in people, without needing to cause discomfort.
Hair loss can sometimes be treated via medications or steroid injections, but more effective therapies are being developed, such as the use of stem cells or drugs that wake up dormant hair follicles.
The Daily Mail further explains:
Next, the experts wanted to see the effect of fatty acids on skin without the use of any chemical irritant, so they created serums made of different fatty acids dissolved in alcohol, such as oleic acids and palmitoleic acids.
Promisingly, researchers found these to be effective in promoting hair regeneration when applied to skin without the irritant.
They have patented their serum and plan to test different dosages of the serum on people’s scalps before hopefully marketing it – although as yet it’s unclear when this would be and how much it would cost.
