Risk factors for Premature Hair Graying
Hair graying results when melanocytes stop producing melanin, the same pigment that darkens our skin to protect us from UV radiation. Sex steroids such as estrogens and progesterone stimulate the function of melanocytes. Also, premature hair graying is less frequent in ethnic groups, notably blacks, who also tend to have higher testosterone levels in both sexes. [J Clin Endo Metab 1997; 82: pp.3580-83]
Premature Hair Graying suggests the following may be present
Is premature graying of hair associated with other features of accelerated aging – faster bone loss, for example? A study of 293 postmenopausal women has confirmed that early hair graying and greater bone loss tend to occur together. The lower bone density was especially apparent in the hip region.
The authors found that when they adjusted bone mineral density for age and weight, there was a clear connection between the age of onset of hair graying and bone density. “Age- and weight-adjusted bone mineral density (BMD) was significantly lower in those with the majority of their hair graying during their thirties compared with those in whom it occurred in their forties.” Premature hair graying before the age of 40 was associated with a lower BMD at most skeletal sites. Also, women who started graying extremely early in life, already in their twenties, had lower bone density than those who started graying in their thirties. [J Clin Endo Metab 1997; 82: pp.3580-83]
Recommendations for Premature Hair Graying
There have been some testimonies regarding partial restoration of hair color during the long-term use of hydrogen peroxide baths. Head hair color may move slightly away from white toward its earlier color. Men’s chest hairs may recover their natural color to a greater degree than head hair. We do not know if any study has investigated this possible benefit.

A dark pigment produced in the skin. Dark-skinned individuals produce more melanin, and melanin production increases in response to sunlight, causing the skin to become darker.
Any of a large number of hormonal substances with a similar basic chemical structure containing a 17-carbon 14-ring system and including the sterols and various hormones and glycosides.
The principal male sex hormone that induces and maintains the changes that take place in males at puberty. In men, the testicles continue to produce testosterone throughout life, though there is some decline with age. A naturally occurring androgenic hormone.
Plays a vital role in regulating many body functions. They act as catalysts in nerve response, muscle contraction and the metabolism of nutrients in foods. They regulate electrolyte balance and hormonal production, and they strengthen skeletal structures.
