And it often starts earlier: About 25 percent of men who struggle with thinning hair and excess hair loss can noticeably tell the difference by the time they turn 21.
Luckily, there are many options for how to fix thinning hair in males, including diet, lifestyle changes and medications. Read on to regain locks you’ll love.
The average guy is born with 100,000 hair follicles (each of which makes and holds a single strand of hair at a time) on his head. This hair follicle count remains consistent throughout life.
What doesn't always stay the same, however, is hair health and how much hair thins over time. Hair follicles can also stop growing hair, or simply shed more throughout each day.
A typical person sheds about 50 to 100 hairs daily, and anything beyond that can be defined as excessive hair loss.
Anagen stage: The strand of hair is actively growing. This generally lasts two to six years.
Catagen stage: During this roughly three-week transition phase, the hair strand stops growing and is getting ready to shed.
Telogen stage: The strand of hair is expelled from the follicle. After the hair sheds, the follicle remains dormant for about three months before sprouting its next strand of hair.
Male pattern hair loss is often caused by genetics, habits, other health conditions or a combination of all of the above. The most common causes of hair thinning among men include:
Over-treating hair, using harsh products or washing hair too often
Wearing tight buns or hats
Not eating a well-balanced diet, which includes enough iron, folic acid and other minerals that fuel normal follicle growth
Chronic stress, which can cause cortisol levels to spike, and lead to extra hair loss
Fast weight loss, or about 20 pounds or more in a few months
Skin infections or disorders
If you’re noticing hair thinning so severe you can see the difference, it can be wise to meet with a healthcare professional to discuss your hair health and how to increase hair growth.
To diagnose hair thinning, a healthcare provider may ask about:
Your current diet, including any recent changes
Preexisting medical conditions
Family history of hair thinning or medical conditions that could cause it
After an exam and/or discussion, if your healthcare professional is unclear, he or she may work with a laboratory to test your hair or scalp samples, or order blood tests to ensure you don’t have other health conditions besides hair thinning.
Home remedies like essential oils are commonly touted as solutions for how to fix hair thinning. But according to the pros, the methods below are the best hair loss treatments available.
With zero side effects and no cost, this is the ideal first step in your quest for healthier and thicker hair.
As you wash your hair—using both shampoo and conditioner to keep it hydrated and strong—use the pads of your fingertips to gently apply pressure on your scalp to stimulate blood flow.
A thickening shampoo is designed to not only add volume to your hair, but is also infused with vitamins and amino acids for a healthier scalp that will grow more healthy hair.
“I tried several different options before but Hims combined approach of all four methods by far created the best results.”
“Hims has been the greatest confidence boost, no more bald jokes! I look and feel so much younger!”
“When I show my barber my progress, he is always in disbelief. I have to recommend Hims to any guy who’s experiencing thinning.”
“Cost effective and affordable. My hair keeps growing thicker, fuller, and at a fast rate.”
“I noticed a huge change in the overall health and fullness of my hairline.”
“Now after 5 months I’m able to style waves first time in 10 years!”
“I decided to jump right in and I'm so glad I did. I definitely feel ten years younger!”
“In just as little over two and half months, I can really see the difference in thickness and in color.”
“4-months strong and my confidence boosted back up to 100% using Hims, future me really does thank me.”
“I’m a 34 year old father of two and have been using Hims for over a year now. My hair is back to what it was in my mid twenties.”
For some patients, depending on the severity and circumstances of the hair thinning, doctors prescribe a daily pill like finasteride (Propecia) instead of topical treatments.
Unlike topical treatments for hair thinning like Minoxidil, this is only recommended for men due to potential side effects. Finasteride is also available in spray form (topical finasteride) if you prefer that to a pill.
Minoxidil is an over-the-counter liquid or foam hair loss and hair thinning treatment approved by the U.S. Food and Drug Administration (FDA).
Apply minoxidil consistently and you should see results within a few months; often quicker if you use it in tandem with finasteride.
Spironolactone (Aldactone) is typically prescribed as a “water pill,” but is also used for men whose thinning hair is a result of excess androgen production.
A blood test can pinpoint if androgen could be the cause of your hair thinning—and if it is, this could be a great hair loss treatment option.
In addition to these hair loss treatment options, a healthy diet can help keep your hair growing long and strong.
Aim to consume a well-balanced diet with a mix of all macronutrients, including protein, fat and carbohydrates.
The best foods for hair are ones that provide enough of the essential vitamins and minerals involved in hair growth, including vitamin A, vitamin B12, vitamin C, biotin, selenium, omega-3 fatty acids, iron, calcium and zinc. (Ask your healthcare professional if you might benefit from a blood test to see if a multivitamin or specific biotin supplement could fill any dietary gaps.)

As always, it’s wise to check with a healthcare professional, to help determine the cause of your hair thinning, and to pinpoint the best treatment options for you.
