Prime Culprit: Hormones
The premier cause behind hair loss in both men and women is hormonal. Hormonal changes, deficiencies and excesses are the main cause behind pattern baldness, or androgenic alopecia. The male-sex hormone behind pattern baldness in men is DHT. Dihydrotestosterone (DHT) is a by-product of testosterone, which can stimulate the receptors in your hair follicles, causing them to shrink, weaken and eventually stop producing hair altogether. At present there is no final cure for male pattern baldness, but hair loss medications like Propecia and Minoxidil can help arrest further hair loss, and hair transplants offer a permanent solution to the problem. Non-surgical and non-medical hair restoration shampoos like groMD and Nizoral are also known to lessen DHT levels in the scalp and strengthen hair overall.
Father Time
Not every person will lose their hair – even if your close relatives have gone bald, there are no guarantees that you will too. However, with age usually does come some degree of hair loss or thinner quality hair. By the age of 60, around two-thirds of men will have some hair loss, and around 70 per cent of women will experience hair loss around the age of 70. Depending on the cause of the hair loss, it may be treatable, so if you have any concerns, get in touch with our Modena Hair Institute team.
Stress
You might not have known or even believed this, but high stress, even in short episodes, can directly cause hair loss in individuals with no previous hair loss experience. Telogen effluvium – trauma or stress-induced hair loss – is a result of your fluctuating hormones sending the hair growth cycle into a state of shock, forcing the hair to go into a resting phase. Many follicles can be affected at the same time, which is why it may seem like you’re losing a significant amount of hair. As with post-natal hair loss, it’s usually only temporary, so focus on maintaining good habits with sleep, exercise and diet to keep your stress levels down in the meantime.
Harsh Weather and Excessive Sun Exposure
A change in weather can bring a change to your hair condition – and hydration is usually the culprit. Hot summer days or harsh winter nights are not always your hair’s best friend, as harsh weather exposure can damage your hair, making it dry and brittle. The UV radiation of the sun can damage the proteins that the hair is made from, so if you know you’ll be spending a lot of time outside, invest in a good hair follicle spray like groMD. Thankfully, if you do get sunburned on your scalp, although you may lose a few hairs if your scalp peels, the chances are it will grow back.
