Hair growth and thickness wane dramatically as we age, especially in men. Once men cross into their late 30s and early 40s, hormonal imbalances can occur. High androgen levels and nutritional deficiencies can both cause hair fall, damaging your hair follicles and speeding up male pattern baldness.

However, using the right supplements formulated to address the root cause of your hair loss can help promote hair growth and thickness. These are the 3 best supplements to promote hair growth in men over 35 years of age.

3 Best Hair Growth Supplements for Men Over 35

1. Best for Hair Growth and Hair Loss Prevention

Certain herbs such as stinging nettle root and saw palmetto can inhibit DHT production and promote hair growth. While some hair growth supplements work on stopping DHT production, others provide essential nutrients important for healthy hair growth.

Approved Science Hairprin™ leads the race, as it simultaneously addresses both problems. This scientifically formulated supplement promotes thick hair by stopping chronic hair loss and promoting rapid regrowth. It contains L-cysteine, L-methionine, biotin, vitamin A, and vitamin B complexes, which help strengthen hair structure and provide the building blocks required to maintain healthy hair production.

The other active components in Hairprin™ include flavones and ginkgolides, which increase blood flow and the delivery of nutrients to the scalp, accelerating hair growth and preventing hair loss.

Biotin by Approved Science


A biotin deficiency can be the reason behind your hair fall. Nevertheless, this water-soluble vitamin acts as a cofactor for certain enzymes responsible for skin, nail, and hair health. Biotin helps convert the food you eat into energy for the body, maintaining a healthy metabolism and allowing your body cells to function at their best.

Approved Science Biotin MD™ contains 10,000 mcg of biotin for optimum health benefits, including improving hair health for thicker, stronger hair follicles.

Besides its beneficial effect on hair growth, Biotin MD™ keeps the nervous system healthy, has anti-inflammatory benefits, lowers the risk of cardiovascular disease, and plays an important role in repairing and building damaged tissues.

Manufactured in the USA in an FDA-recognized and cGMP-approved facility, this supplement is the best choice for hair health and thickness.

Reduce Hair Loss Effects With the Right Supplements

Dietary supplements help bridge nutritional deficiencies that cause hair loss. The best vitamins for hair growth are biotin, vitamins A, D, and E, and minerals such as iron and zinc.

However, men aged 35 and above may need something more potent and specifically formulated to target underlying hormonal issues as well. The products on this list address the causes of hair loss and can help grow thicker, healthier hair.

When choosing the right supplement, make sure you make your pick according to your specific hair needs.
