On average it takes 15-25 years for men to go completely bald. This process can begin at any age. About two thirds of men are either bald or have a balding pattern by the age of 60. In a nutshell, there is no particular age when you can expect to see hair loss.
By the time you turn 30, you have a 25% chance of displaying some balding. By age 50, 50% of men have at least some noticeable hair loss. By age 60, about two-thirds are either bald or have a balding pattern. While hair loss is more common as you get older, it doesn't necessarily make it any easier to accept.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
A receding hairline is a classic early sign of balding. You'll notice the signs of a receding hairline if your hair begins to thin at the temples, creating a more prominent widow's peak and a hairline that resembles the letter M or a horseshoe.
Although hair loss is often associated with older men, it can begin at any age, including in your mid-20s. Most hair loss in men is caused by androgenetic alopecia, or male pattern baldness — a form of hair loss that's linked to hormonal and genetic factors.
And it strikes a lot of them. By the age of 30, about 30 percent of men have male pattern baldness; by age 50, about 50 percent join the club. And by age 70, 80 percent of men have some sort of baldness, said Dr.
About 70% of men will lose hair as they get older. And 25% of bald men see first signs of hair loss before age 21. “Recent advances offer a lot of hope in both treating and preventing different types of baldness,” says dermatologist Amy Kassouf, MD. For example, researchers can now grow hair follicles in a lab.
The X or female chromosome carries the primary baldness gene, and men inherit this X chromosome from their mothers. This makes the hereditary factor around baldness most dominant on your mother's side.
Hair loss can be due to over 40 different causes
There are several other causes of hair lossincluding medical illnesses like thyroid, or diabetes; stress, certain medications can cause it too like anti-coagulants, blood thinners, etc, nutritional deficiencies, hormonal imbalance, crash dieting, and oral contraceptives.
Male pattern baldness tends to be hereditary and runs in families. Sometimes men go against family traits and lose hair even if their male relatives don't. This may be due to the baldness gene skipping a generation or lifestyle choices switching the gene on.
Is Hair Color Inherited from Mother or Father? Hair color comes from both parents through the chromosomes passed onto their child. The 46 chromosomes (23 from each parent) have genes made up of DNA with instructions of what traits a child will inherit.
Certain races have higher rates of hair loss compared to others. Caucasians have the highest rates out of all the ethnic groups. On the opposite end of the spectrum, Native American Indians, Inuits, and Chinese have the lowest rates.
You might be able to reverse hair loss, or at least slow it. With some conditions, such as patchy hair loss (alopecia areata), hair may regrow without treatment within a year. Treatments for hair loss include medications and surgery.
Dihydrotestosterone or DHT
Dihydrotestosterone or DHT is an androgen, which is a male sex hormone that helps men to develop male-body characteristics. DHT is also the reason behind pattern baldness among men when they get older. Though women also get affected by DHT, the number is much lesser than men.
Some people who don't lose their hair have low levels of the enzyme that converts testosterone, and so more recently researchers have been seeking ways of blocking the enzyme in others. A treatment called finasteride works on this principle, but it is expensive and needs to be or hair loss begins again.
Nearly all men have some hair loss by the time they are in their 60s. However, the age the hair loss starts is variable. About three in ten men aged 30 years and half of men aged 50 years have significant balding. A similar condition affects women but in a different pattern.
Which country has the most baldness? With almost half (42.79 percent) of men going bald, baldness is most common in the Czech Republic. Just shy of the Czech Republic, Spain stands in second place with 42.6 percent of men going bald.
Testosterone itself doesn't directly cause hair loss. However, increasing your testosterone levels can also increase your levels of DHT, causing damage to your hair follicles and speeding up the effects of male pattern baldness.
Androgenic alopecia more common in men
Permanent hair loss affects 70% of men and 40% of women in their lifetimes.
Androgenetic alopecia (male pattern baldness) affects between 50 and 80% of Caucasian men, The number of Asian and Afro-Caribbean men who suffer is approximately half that.
The typical pattern of male baldness begins at the hairline. The hairline gradually moves backward (recedes) and forms an "M" shape. A circular area on the back of the head (vertex) often thins and expands in size over time.
Diagnosis. Hereditary-pattern baldness usually is diagnosed by both its pattern and a history of a similar type of hair loss affecting family members. In most people, no further tests are required.
