Hair loss: Dr Ranj discusses causes of male pattern baldness

Hair loss can be attributed to numerous causes but one of the most common causes is the sex hormone dihydrotestosterone (DHT).
It is the key driver behind male pattern baldness - a permanent type of hair loss that usually runs in the family.
Hair loss treatments aim to inhibit DHT in an attempt to reset hair growth.
They often achieve this by inhibiting the enzyme '5-alpha reductase'. This is present in small amounts in muscle and converts testosterone to dihydrotestosterone (DHT).
Evidence suggests rosemary leaf extract inhibits 5-alpha reductase to stimulate hair growth.
In a study conducted on mice, the application of rosemary leaf extract improved hair regrowth.
In addition, the extract promoted hair growth in mice that had their back areas shaved.

In their conclusions, the researchers suggest that the extract inhibits the "binding of dihydrotestosterone to androgen receptors".
This is significant because androgen receptors are proteins that allow hormones like testosterone and DHT to bind to them, thereby causing hair loss.
Consequently, rosemary leaf extract is a "promising crude drug" for hair growth, the researchers conclude.

But most treatments aren't available on the NHS, so you'll have to pay for them.
According to the NHS, finasteride and minoxidil are the main treatments for male pattern baldness.
"Minoxidil can also be used to treat female pattern baldness. Women shouldn't use finasteride," warns the NHS.
Some wigs are available on the NHS, but you may have to pay unless you qualify for financial help.
