About Hair problems
As you get older there will be some natural loss of hair. You know, a few hairs in your comb or brush or a few on your pillow. As you begin to see more hairs than usual in your comb or on your pillow; if you are seeing more "shedding" you might consult your doctor. It may be nothing, but it could be a form of Alopecia.
In women hair problems begins with thinning hair all over the scalp. In men it begins at the temples and progresses toward the back of the head sometimes resulting in hair on the sides and back of the head and sometimes in complete baldness.
How does this happen? Hair fall out can be caused by many things. One very common cause is the presence of DHT-dihydrotestosterone (a male hormone). This will result in the shrinkage of the hair follicles which forces the hair to fall out. It weakens the hair shaft as well. This reduces the amount of hair that is visible.
Other causes include stress, major surgery, illness, very high fevers and some medications. The use of birth control, pregnancy, and childbirth can also cause hair to fall out. This hair problem though is usually temporary. The most common medications that cause loss of hair during birth control are chemotherapy and radiation treatments. Once the medications are suspended new hair will grow over time.
How Hair Shampoos Work
Most treatments has something in them to break down the DHT. This will hopefully allow the hair follicles to heal and return to normal size. DHT blockers can help prevent damage to the hair follicles and then will stop baldness. The now healthy hair follicles will likely allow new hairs to grow.
Hair loss shampoos may also help to clear out the pores of the scalp. This will allow nutrient to reach the hair follicles more effectively. With the proper nutrients hair will grow normally.
Some hair shampoos may also treat irritated scalp. They may also give you relief from itchiness. A healthy scalp will allow hair to grow. There may be minimal loss that is likely due to getting older and is considered normal.
Hair shampoos work in a number of ways. They may help relieve scalp conditions, open pores allowing nutrients to more effectively reach hair follicles, and they may block the effects of DHT-dihydrotestosterone; damaging and shrinking hair follicles. A healthy scalp will give your hair a greater chance of being healthy and stop or prevent hair ailments.
