Generally, people begin noticing signs of hair loss in their 30s and 40s. More significant hair loss often happens when people reach their 60s and beyond.
Normally, hair loss starts between the ages 18-25 in most men. When a man passes his 35-40 age, hair loss usually slows down and after the age of between 50-60, it increases again. This information shows us that the process of hair loss is progressive and throughout life. But there are always exceptions to the rule.
Male pattern hair loss progresses rapidly between the ages of 20-30. After the age of 30-35, shedding starts slowing down, as the levels of androgens in the blood start reducing. In older men with androgenetic alopecia, the hair loss slows down even more.
Although we usually associate hair loss with middle age, it's quite common to begin to lose hair before the age of 25. In fact, research shows that approximately 16 percent of men between 18 and 29 years of age are affected by moderate to extensive hair loss.
Can thin hair become thicker again? A person cannot change the texture of their hair. However, the hair may grow back after chemotherapy or pregnancy, for example.
Effective treatments for some types of hair loss are available. 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.
Biotin. Biotin, also known as vitamin B7, is a complex B vitamin that is often touted for having hair growth benefits. And some of that hype may actually be worth it. Biotin has functions in “creating red blood cells, which carry oxygen and nutrients to the scalp and hair follicles,” says Dr. Green.
Hormonal changes, autoimmune diseases, thyroid disorders, and stress are among the known causes of hair loss in young men and women. However, diet can also strongly influence hair health. The growing popularity of vegetarian and vegan diets could be contributing to millennial hair loss.
For younger women, thinning hair is usually a result of poor nutrition, stress, disease, or changes in medications, like birth control. Crash diets, weight loss, and low iron levels are all reasons why you may notice hair falling out or changes to hair growth.
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. Or your hairline might seem to recede or thin all the way across (Murphrey, 2021).
It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men. Baldness typically refers to excessive hair loss from your scalp. Hereditary hair loss with age is the most common cause of baldness.
Hair Loss in Your 30s and Beyond
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.
Thankfully, technology has advanced so that you can actually grow your own hair back with a minimally-invasive, more heavy-duty treatment. With a follicular unit extraction (FUE) treatment, surgeons can transplant viable hair follicles and implant them in bald spots.
As you age, some follicles stop producing hair. This is referred to as hereditary hair loss, pattern hair loss, or androgenetic alopecia. This type of hair loss is typically permanent, which means that the hair will not grow back.
Sources of Biotin
Foods that contain the most biotin include organ meats, eggs, fish, meat, seeds, nuts, and certain vegetables (such as sweet potatoes) [2,12].
If you are experiencing thinning or balding, our Bosley experts recommend washing no more than three times a week.
The bottom line. There's no strong evidence to support using biotin for hair growth or to prevent hair loss in people without a deficiency. Because hair thinning and poor hair growth are sometimes associated with a biotin deficiency, correcting a deficiency can help restore hair growth in some people.
