Crescita dei capelli: come avviene e come velocizzarla

Hair growth is a process that occurs in different stages, from growth to rest and fall.

We can start talking about hair loss when they fall out and are not replaced by new ones.

Some of daily habits such as hair washing and especially diet can definitely affect hair growth.

How hair growth happens

The process of hair growth is very articulated and has a variable duration. Each hair follows its own life cycle independently of the others. We can highlight 3 different phases for each of them:

• • Anagen growth phase: during this first phase the birth of the hair and its growth takes place. The duration of the anagen phase is variable from 3 to 6 years; most of the hair in our hair is in this phase.
  • Catagen “quiescence” period: has a shorter duration than the previous one: about 3 weeks. In this phase there is a transition of the hair that stops growing and moves towards the resting phase.
  • Telogen resting phase: this last phase of the hair life cycle occupies approximately 3 months. During this time, the hair follicles cease their activity, the hair falls out and falls off.

The telogen resting phase: this is the last phase of the hair life cycle and occupies approximately 3 months.

The life cycle of hair growth and hair loss described, under natural conditions, leads to a daily loss of as much as 80-100 hairs. However, these are readily replaced by new hair in the anagen phase that grows underneath the newly lost hair.

If this does not happen, it means there is an imbalance in the growth process and, as a result, we start talking about hair loss. This phenomenon, called baldness, affects both men and women.

What habits affect hair growth

Washing and drying hair

Washing your hair properly has an effect on regrowth as well. It is not recommended to wash your hair daily with shampoo to avoid damages and dryness. It is better the use of natural products or oils to cleanse the scalp from external agents as an alternative.

Another recommendation would be the use of towels instead of phon, as excessive heat can damage our hair and scalp.

At last, when it comes to comb hair, it’s better not to opt for a too tight ponytail in order to avoid a long-term damage

Food

Food plays an important role in hair growth. In fact, nourishing our hair from the inside out is the first step in taking care of it. Some foods allow us to keep our hair in shape more than other ones. Here are some examples:

• Fatty fish: thanks to their high omega-3 content, consuming these foods allows us to nourish the sebaceous glands. In this way, the hair takes on shine and stays healthy. Some examples of fatty fish are salmon, mackerel and cod.
• Vegetables: especially orange ones, such as carrot or pumpkin, are rich in vitamin A, which helps lubricate the skin and moisturize the scalp.
• Fruits: classic examples are blueberries, kiwis and strawberries. All of these are an excellent source of vitamin C.
