Hair growth depends on an adequate diet. A widespread diet problem which causes loss of hair is iron deficiency Anaemia. The cause is too little iron in blood, brought on by a diet containing too little meat, eggs, cereals or peas and beans. Fresh fruits and vegetables are also needed to provide vitamin C, which enables the body to absorb iron.
Cutting the hair
Although cutting the hair is not essential to its well-being, it is easier to keep the scalp clean if the hair is kept reasonably short. Regular cutting does not make the hair grow strong or faster.
How hair can be damaged
Although scalp hair is hardy, and can withstand a lot of abuse, it can be damaged by too much or inexpertly applied perming, dyeing, bleaching and massage. The amount of beautying the hair can take varies from person to person. Occasionally the scalp is allergic to the dye and becomes inflamed and swollen. To prevent this occuring, the dye should be tested by applying it to a small area on the arm. If a patch of inflammation has developed, the dye must not be used on the hair.
Most people who bleach their hair do so with hydrogen peroxide. If the peroxide is repeatedly applied, it may make the hair brittle. If this happens the hair may turn rough, develop split ends, or become thinned or shortened.
