No Proteins in the Diet
Check your diet again and see if it lacks protein to a considerable extent. Sometimes you may even not notice it, but your diet lacks in a lot of necessary ingredients. Protein is very necessary for proper health of hair, because hair is made of protein. If you have a very busy schedule and you are not taking breakfast, lunch and dinner on correct times, or skipping any of these, you may lack in many ingredients including protein. Loss of hair starts within two to three months after your protein intake drops.
Cure is quite easy – start taking enough protein! Eat a lot of fish, meat (lean), eggs, dairy, nuts, beans, and more. Rather than taking synthetically formulated medicines, these natural remedies for thinning hair are definitely safer and more effective. Even though you are a vegetarian or vegan, you need not worry. There are lots of vegetarian food products which are rich sources of proteins, for example, all peas and beans, most grains and especially quinoa, nuts (cashews, almonds, pistachios) and nut butter, seeds of poppy, sesame and sunflower, non-dairy milk (soy milk, rice milk, almond milk), cocoa powder, and more.
Hair loss can be genetic too. If you have a family history of women losing hair at a certain age, then you are prone to it. This is female pattern of alopecia (baldness) wherein hairline doesn’t recede unlike in men, but parting widens and the skin of scalp shows out.
In such a case, you can use vitamins for thinning hair and at least reduce hair loss and maintain whatever hair you have.
Birth Control Pills
Just as in pregnancy, your body’s hormones can affect your hair health. Switching from one birth control pill brand to other or stopping them altogether also can cause temporary hair loss or telogen effluvium. Again, this is more likely if you have a hereditary tendency of hair loss. Similarly, the hormonal imbalance during menopause may also give the same effect. In this situation, the androgen receptors in the scalp are activated, the hair follicles are miniaturized and hair loss starts.
The remedy here is talking to your doctor. If a new brand is causing the problem, switching back to the old one may be a solution. You need not worry much about this as this type of hair loss too is temporary.
There are more answers than these to the question what causes thinning hair, like emotional stress, anemia, hypothyroidism, deficiency of vitamin B and D, auto-immune hair loss, lupus, severe weight loss, polycystic ovarian syndrome (PCOS), some medicines like blood-thinners and antidepressants, excessive styling of hair, aging, and some other reasons like chemotherapy, and some diseases.
