After nearly 50 years experience and an A level in science, I can tell you that very little can be done to permanently correct damaged hair, that DOESN'T involve a pair of scissors. By damaged I mean hair which has been chemically OVER processed-a poor colour choice on its' own, won't. Several attempts to rectify it, WILL. Hair which has been exposed to a mixture of chlorine and too much sun can be considered to be damaged. As a result of these accicidents to hair, if the thought of the scissors terrifies you, there are products out there which give temporary help. The bottom line is, damaged hair is porous, so can therefore absorb, TO A POINT. If hair was fully absorbant, we would all be waterlogged. The conditions I've spoken of so far are induced, the following are systemic. Hair will reflect your state of health, but you probably won't notice it at the time because hair only grows at about 1/2 an inch per month. ANY chemical in the bloodstream will eventually find its way to your hair because blood capillaries feed the hair follicle. Chemotherapy may cause the hair to fall, but often, a new, and drug free growth presents as better than the hair which has been lost. Whilst there are products which will improve the appearance of MOST hair types, there will always be those hairtypes which recieve little or no benefit from them. Generally speaking the hair type which benefits most, from any shampoo/treatment is hair which is dimentionally thicker. Those with very fine hair often find that the more "luxurious" the product, the less it will do for their hair, this is usually because it's too rich for very fine hair, thus causing it to be unmanagable, and people always use too much. When it comes to amounts used, less is always more, you can add more if necessary but remember that in the end, all those lovely bubbles end up down the drain. Whatever amount the manufacturer suggests, try half the amount first. There are some wonderful products which will make hair appear thicker, but the key word is always "appear". There was a time when a mixture of sugar in water was used to do the same thing, and I have no doubts about its efficiancy, especially now, in the days of daily hair washing, if used in the right quanties.
