Here's the truth: You can't change the size of your hair follicles. If you were born with fine hair, it's genetics, and no product will completely alter that. Of course, there are ways to maintain your hair health, add volume, and keep it from getting any thinner.
Your hair will grow thick and fast if your diet has enough calories and nutrients. Hair needs nutrition. Grow hair faster and thicker at home by eating a diet that provides enough protein, selenium, vitamins, and other micronutrients and using home remedies.
Lifestyle factors could include using certain hair products, wearing your hair up too tightly, experiencing high stress levels, or not getting enough of certain vitamins and minerals in your diet. People who have immune system deficiencies could also have thinning hair.
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.
To get thicker hair, eat a healthy diet with omega-3 fatty acids, B vitamins, iron, and vitamin D. For thicker hair, it's important to use a sulfate-free shampoo and to stop using heat styling products like flat irons or curling irons.
“Vitamins are essential for healthy hair growth and may help in preventing hair shedding and thinning,” says Michele Green, M.D., a cosmetic dermatologist in New York. “The best vitamins for hair growth include B vitamins, vitamin D, vitamin E, zinc, biotin and iron.
“Be sure to get plenty of good-quality protein and good fats like olive oil and omega-3s.” She recommends salmon, avocados, nuts, vegetables, and fruits to get all the key nutrients needed for growing stronger hair.
Many men wonder whether they need to pursue treatment to reverse the effects or if they can grow the hair back on their own. Although hair re-growth may be possible, you should also know when to seek professional help. If the reason for thinning hair is genetics, it will not grow back on its own.
Use a volumizing shampoo or thickening shampoo.
Thickening shampoos work by infusing the hair with proteins, vitamins, polymers, and/or moisture that plump up each strand making each piece appear thicker. This is ideal for boosting thickness in fine hair types.
If you are experiencing thinning or balding, our Bosley experts recommend washing no more than three times a week.
Takeaway. Your body makes enough biotin on its own through your dietary intake each day. Therefore, you shouldn't take biotin supplements unless directed by your doctor. There are some rare health conditions that can cause some people to need biotin supplements on a regular basis.
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].
Trying to grow hair too long
Unfortunately, that also makes thin hair harder to grow out. “With fine hair, it breaks off so you can't usually get it really long,” says Reyman. If you don't have much density, ask your stylist to help figure out the longest your hair can grow while still looking good, says Broderick.
Only riboflavin, biotin, folate, and vitamin B12 deficiencies have been associated with hair loss.
Biotin. Biotin, also known as vitamin B7, stimulates the production of keratin to increase follicle growth. Biotin deficiencies tend to be rare, with those diagnosed with Biotinidase Deficiency being the most common.
Some of the best sources of biotin include legumes, egg yolks, organ meats, nuts, seeds, mushrooms, avocados, sweet potatoes, and yeast. Biotin supplements are available as well, but most people can get all of the biotin they need by eating a balanced diet.
The hair cycle and hair follicle structure are highly affected by various hormones. Androgens—such as testosterone (T); dihydrotestosterone (DHT); and their prohormones, dehydroepiandrosterone sulfate (DHEAS) and androstendione (A)—are the key factors in terminal hair growth.
