Hair loss is a common problem in men and women of all ages, who experience thinning hair. Even if you notice only a few hairs coming out when you shampoo or brush your hair, it’s time for action.
If you are suffering from hair loss, it may be a result of poor nutrition, stress, trauma, medications, or genetics.
Men are most likely to experience gradual thinning of hair on the crown (receding hairline), but an increasing number of women also suffer from genetic or hormonal causes of thinning hair. More than 95 percent of men experience some degree of hair loss during their lives, according to the American Hair Loss Association.
Nutrition plays an important role, too
Vitamins and minerals (such as vitamin A, vitamin B, vitamin C, vitamin D, vitamin E, iron, selenium, and zinc) play an important role in non-scarring alopecia. Micronutrients are major elements in the normal hair follicle cycle, playing a role in cellular turnover, according to research.
Iron, vitamin D, folate, vitamin B12, and selenium are vitamins and minerals that may be involved in hair graying/whitening. Supplementing these deficient micronutrients can improve premature graying.

Works Well & I Will Buy Again
“I’ve experienced good results with the Happy Head formula in a relatively short time and I will continue to use the product. Thank you very much for providing a more desirable, yet effective alternative to ingesting a drug internally, thus better avoiding the possibility of experiencing any negative side effects.” Mike G.
It’s Really Working
“I’ve only been using Happy Head for 2 1/2 months, and I’m seeing legitimate improvements already! I’ve used other products that either didn’t work at all or made my scalp super sore, and this feels very easy on the skin in comparison. My receding hairline definitely looks a lot fuller again, can’t wait to see how it looks in a few months!” Max B.
Good Stuff
“I’ve been taking Happy Head since January, it’s June, and my hairline is restored. I started seeing results within a month. My right temple has been thin since 2011 – it’s now restored. I recommend topical fin/min and Happy Head seems to deliver it. Good customer service, I had one or two issues that were sorted out quickly / easily.” Cullen R.
