If you're male, there are a few things you could want to avoid in life.
One of those is male-pattern baldness.
That begins as a receding hairline or even a bald spot on the top of your head, and can eventually lead to complete baldness after a severe case of hair thinning and hair loss.
But dermatologist Dr Loretta Ciraldo has provided an easy way to spot the early warning signs.
She explained to Gear Patrol: "There is no true preventative to use to prevent hair loss,
"Hair loss is progressive, and happens over the span of decades — even if it begins in your 20s or 30s.
"The two most obvious 'early signs' of hair loss that we notice are shedding more hair especially when we shampoo and on our clothes during the day, and that our part appears wider."
However, there is one important thing to be aware of when you start aging.
"But we have to remember that as we age, our hair shafts thin to make it appear as though we've lost hair when we may have a healthy amount of hair but each hair is just thinner," Dr. Ciraldo says.
Furthermore, Dr Ciraldo has urged men to be particularly aware of hair loss, particularly if it reaches a certain number of hairs.
"Do not take it for granted that hair thinning or increased hair loss is solely due to ageing. If you are losing more than 120 hairs in a day please see the dermatologist or your primary care physician to determine the cause of the hair loss. It may be related to a number of causes including but not limited to thyroid issues, anemia, or drugs you are taking." she added.
