The problem of thinning hair may be caused by a genetic predisposition that comes from a family history of thinning hair. Health problems such as Hyperthyroid or Hypothyroid conditions; medications such as chemotherapy, any hormone replacement medications including birth control pills are culprits often overlooked.
It is normal to shed some hair each day as part of this cycle. However, some people may experience excessive (more than normal) hair loss. Hair loss of this type can affect men, women and children.
Are you Stressed?
Thinning hair can also be attributed to stress and trauma that can cause constriction of blood supply and poor vitamin assimilation to the scalp and hair. Or, simply from poor nutrition and diet that can include a high consumption of animal fat, high protein and fad diets. Even external environmental toxins and pollutants, such as chlorine, metals, minerals and water pollution cannot be ignored. All these factors can be causing your clients' hair to look thinner.
Under a microscope
The hardening prevents hair growth. The hair cycle slowly becomes disrupted and more hair is shed than normal. In time hair growth stops completely and baldness results. Here you see an example of a hair follicle as seen under a microscope.
Age and hormones
Most people naturally experience some hair loss as they get older. But age, changing hormones and heredity cause some to lose more hair than others.
Female-pattern baldness starts with the replacement hairs becoming progressively finer and shorter. They can also become almost transparent.
It has been recorded that about 50 percent of women experience hair loss have female-pattern baldness! Unfortunately, it is often permanent just as in men. Not all hair thinning and loss must be permanent. There has been various cases of perimenopausal women, for example, experiencing thinning and lost hair who, once their hormone levels become balanced, can experience the thickness of previously thinning and the regrowth of lost hair that occurred during the ebbing and flowing hormonal years.
Get Wavy! Permanents can help give volume to fine-textured hair — but hair must be healthy, not dry or brittle. Only a gentle body wave is advised, because tighter waves can damage the hair. Because chemicals in permanents are harsh, a permanent should be only a last resort for fine-haired people.
