7 comments on âOcean Sunfish are the most useless animal (an epic rant)â. 1  Man alive, when are humans going to realize the world wasnât made for them? 2  So what if this animal grows as nothing more than a source of food for others.
The most important hormones affecting the health of skin, hair and nails are estrogen (especially in proportion to testosterone), thyroid hormones and cortisol. Estrogen: Not surprisingly, estrogen levels affect every part of the body, including hair, skin and nails.
These natural products do, on occasion support the shine or growth of hair, skin, or nails. However, slow growth of fingernails and toenails may suggest any nutrient insufficiency so isolating biotin or silica is slightly myopic. What is more common than a deficiency of biotin is changes in hormone levels as women age.
