Health may not seem important until you don’t have it anymore. Reality shows may seem real but real life is different than an edited for television show. Healthy choices in the present can help protect and prevent problems later. Hair growth gets joked about but it can be a sign of health or lack of nutrients in some cases and in other people it is just a genetic difference or an age difference. Male facial hair requires genetics, age and testosterone for some types of hair growth. A few links about it are included in this post along with a brief note about nutrients for cardiovascular health. The nutritional need for healthy hair growth and a healthy heart are similar.
Iodine is essential for women and men and growing healthy babies.
Genetics is involved in individual differences but the underlying need for essential nutrients helps a variety of issues in the body not just ability to have a healthy cardiovascular system, https://www.ncbi.nlm.nih.gov/pubmed/16522926,
or a good testosterone level and healthy hair growth of eyebrows, or on other areas of the body.

Oversupplementing of some nutrients (selenium, vitamin A and E) may be harmful rather than helpful to hair growth and other health symptoms. Selenium and iodine in balance are needed, and adequate vitamin A and E also, Other nutrients that seem involved in hair growth include vitamin D, the B vitamins folate, niacin, and biotin, and the trace minerals iron and zinc are also needed. Simple protein malnutrition alone or lack of some amino acids can lead to sparse hair growth. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5315033/
A recent post was short but important, many nutrients work together to support a healthy body and cardiovascular system:
Whether nutrient deficiencies or other metabolic imbalance is the cause is not clear or it may be a response to oxidative stress, however levels of the trace nutrients magnesium, selenium, zinc, and vitamin D3 were found to be low and the level of calcium elevated in myocardium, a type of muscle tissue in the heart.
