Are you curious about how hair grows on the head? Discover all the stages of the hair growth phase as described in the health magazine Medical News Today. Note that the anagen phase can take months or even several years. Because not all hair follicles grow the same way.

  • During the anagen phase, blood circulates throughout the body. It provides the skin with the oxygen and nutrients necessary for the development of protein cells contained in the hair root.
  • The hair bulb regenerates and the protein cells begin to multiply to form hairs that rise through the skin, more precisely, through the sebaceous gland.

In general, hair growth is faster on the top of the head than on the temples.

What are the factors that impact hair growth?

Hair grows, stagnates and falls out during the telogen phase. They therefore have a life cycle which is renewed several times. But their growth rate depends on several factors including:

  • Genetics: A person’s genes influence how quickly hair grows.
  • Gender: Men’s hair grows faster than women’s.
  • Age: Between 15 and 30 years old, hair multiplies quickly. As they get older, their growth rate becomes slower and stops working.
  • Nutrition: Hair growth can be impacted by diet. Good nutrition is essential to have strong and healthy hair. According to the journal Dermatology Practical & Conceptual in a 2017 report, a diet rich in iron, vitamin D and C is essential for healthy hair growth.
  • Hormones: High levels of testosterone in men and estrogen in women boost hair growth and improve its texture, especially during pregnancy.
  • Stress: it can slow down hair growth and cause hair loss. This factor alone can rest almost 70% of hair.
  • Seasonal changes: Weather conditions and falling temperatures put pressure on the hair follicle, which results in a slowdown in hair growth.

Tips to Accelerate Hair Growth

There is no miracle cure to accelerate hair growth. However, certain daily reflexes promote healthy and optimal hair growth. Dr. Lindsey Bordone, dermatologist at Columbia Doctors, interviewed by the health magazine Healthline takes stock.

  • Avoid restrictive diets: A nutritional deficiency of iron, zinc, fatty acids, selenium, vitamins D, E or A, folic acid is likely to affect hair growth.
  • Opt for a diet rich in protein: to promote hair growth, the recommended daily dose of protein is 50 g.
  • Use caffeine-based hair products: The caffeine in shampoos and conditioners are just as effective as medicinal treatments. Because it stimulates protein cells.
  • Apply essential oils: pumpkin seed oil, rosemary oil, peppermint oil, jojoba oil and even lavender oil are known for their anti-hair loss properties.
  • Massage the scalp: Massage promotes relaxation and relieves stress, which helps dilate blood vessels under the skin. As a result, the hair becomes stronger and thicker.
  • Opt for a PRP treatment: it is the most effective therapeutic option to combat hair loss. This relies on the injection of platelet-rich plasma to stimulate hair growth. To be carried out once a month, for 3 months then every 6 months.
  • Avoid heat: Styling tools like straighteners or hair dryers can damage hair. Limiting their use helps preserve the hair fiber.
  • Avoid going through the coloring box: Frequent use of dyes deprives the hair of natural fatty acids including the amino acids that compose it. Result: they become dry and brittle.
  • Cut your hair regularly: every two months is the ideal frequency to promote healthy hair growth. Split ends must in fact be eliminated to avoid rough and brittle hair.
  • Protect your hair before sleeping: choosing a silk pillowcase helps prevent friction against rough fabrics and tangled hair during the night. Also avoid sleeping with wet hair to get long, healthy hair.


Does trimming your ends improve the speed of hair growth?

Not really. A haircut does not stimulate follicle growth. Because the growth process is directly linked to the follicles of the scalp and not the ends. However, removing a few cm from the ends allows you to obtain healthy strands and thick hair. And it turns out that healthy hair grows faster!

Do some hair types grow faster than others?

Straight hair does not grow faster than wavy hair and vice versa. This is simply a false impression!

What is the hair cycle or hair life cycle?

The lifespan of hair is made up of three phases. The first is the anagen phase. It’s the growing season. The catagen phase only concerns 1% of hair. During this second part of the cycle, the hair is at rest for a period of three months. Finally, hair loss occurs during the so-called “telogen phase” which lasts 3 months. Only 14% of hair is affected by this phase.
