As unfortunate as it might seem, temperatures do take a toll on the hair’s appearance and its health. Whether you are using the hot iron extensively or if the weather is too cold, dry or hot, the rise or fall in temperatures can adversely affect your hair growth. Individuals who deal with extreme temperatures can experience at least a loss of half-an-inch of growth each month. You can, however, make informed hair care choices depending on how your hair relates to a particular temperature.
It might seem surprising to some but cold can also have a negative effect on hair. Medical hair treatments such as chemotherapy and other colder measures can clinically damage the hair. The blood flow to the follicles in the scalp are diminished thus stunting hair growth. Environmentally, cold air can lead to brittleness, fragility, and dryness while increasing the static in the hair. You might try and use some insulation techniques although this may not necessarily give you any results.
Most of us are already aware of the harmful effects of heat. This is also evident by the excessive use of heat tools including hair dryers. Too much heat can damage the hair, make it brittle and lead to split ends. While you may not be able to discard their usage entirely, applying them in moderation may not have extreme negative effects. There are also instances where administration of heat has led to the increase in the flow of blood into the scalp, thus augmenting hair growth. Even hot weather seems to have an adverse effect, with hair becoming susceptible to breakage.
Generally, hair growth rates are affected by the excessive administration of any element or the stress of the situation.
Components of the hair
Hair is made up of proteins or keratin that is also found in the fingernails in humans. In animals, you will find it in claws, horns, and hooves. The cuticle is the thin outer protective layer of the hair, and inside it lies the cortex. A thick layer of melanin determines the colour of your hair. It is the cortex that defines whether your hair is curly or straight. The medulla lies in the centre of the hair fibre and is responsible for reflecting the shine that is emitted from the hair. Finally, the sebaceous glands are located within the root of each hair that is surrounded by the follicle. These glands protect the hair by secreting the right amount of oil to moisturise it.
When hair is over-exposed to a condition, any harm to even one of the above components can lead to hair fall.
There are many ways in which you can stimulate and sustain hair growth naturally. Eat a balanced diet, get regular exercise and practice good hair grooming habits.
