Can Too Little Protein Cause Hair Loss?

Hair usually grows about half an inch per month, although this slows as you age. Each hair remains on your head for two to six years, and during most of this time is continually growing.
But many factors can disrupt this cycle. The result can be that your hair falls out early or isn't replaced.
A new discovery has been made in finding out what actually causes hair loss, namely: the hardening of collagen. Persons who do not suffer from hair loss have supple collagen and persons who begin showing signs of hair loss have hardened collagen. Collagen hardening interferes with the healthy functioning of the hair roots. The vital exchange process of the hair follicle cycle is disrupted and the hair becomes suffocated.
But What Causes Hair Loss?
Diet: Too little protein in your diet can lead to hair shedding. So can too little iron. Bottom line: Too strenuous dieting can result in hair loss! If you want to lose weight, do it the sensible way, especially if you have a hair thinning/loss problem to begin with.
Childbirth: Some women lose large amounts of hair within two to three months after delivery.
Hot Tips!
One great tip is after washing your hair, dry it in whatever manner you normally do. Then turn your head upside down, give your head a vigorous shake, and once back in a standing position, either "place" your hair using your fingers, rather than a brush or comb. You can also use a hair pick to style your hair. The upside down, shaking, also gives a great deal of fullness to otherwise flat looking thin hair. You'd be amazed at how creative you can be with your fingers without pulling at the root of the hair!

For that reason, fine-textured hair benefits from a good shampoo and volume-building conditioner
