Optimal diet for hair health named

Due to the abundance of fatty foods, hair can be lost.

It's no secret that fatty foods can lead to excess weight and then health problems. At the same time, scientists say that high-calorie diets are also bad for your hair.

This discovery was made by scientists from the Tokyo Medical and Dental University. During their research, they found that eating a high fat diet accelerates hair thinning and hair loss.

About research

In their study, the team observed mice. Some of the rodents were fed high-calorie food, the rest were kept on a healthy diet.

As expected, the mice from the first group developed problems with excess weight. The authors found that obesity triggered certain inflammatory signals in their bodies that blocked the regeneration of hair follicles and subsequently led to their loss. This suggests that being overweight may contribute to the depletion of hair follicle stem cells.

We found that hair follicle stem cells in obese mice fed a high-calorie diet turned into superficial skin corneocytes, or sebocytes, which secrete sebum upon activation. In these rodents, hairs fell out faster and a decrease in hair follicles was observed along with the depletion of their stem cells,
– said the lead author of the study, Hironobu Morinaga.

Moreover, these negative transformations took place after 4 days of unhealthy eating . The team also discovered a specific genetic pathway that replenishes hair stem cells. Gene expression in these cells indicated activation of inflammatory cytokine signaling. These signals suppressed the exchange of information in a family of genes called Sonic hedgehog, which play a crucial role in the regeneration of hair follicles.


  • In a healthy person, stem cells are renewed during each hair follicle cycle. This is how the hair continues to grow and gets longer over time.
  • However, as we age, these stem cells begin to malfunction and stop replenishing . Then the hair becomes thinner and begins to fall out.
  • A study in mice proves that eating a high-fat diet can speed up this process.

What foods can improve hair health

It is important that a person's diet contains:

  • Salmon

It is a source of omega-3s, proteins, vitamin B12 and iron.

  • Green vegetables

In particular, spinach, broccoli, cucumbers, etc., contain a lot of vitamin A, which is necessary for the immune function and cell differentiation. But the available vitamin C contributes to better absorption of iron in the body.

  • Legumes

The nutrients in beans and lentils provide the protein, iron, zinc, and biotin needed for hair growth.

  • Nuts

They saturate the body with alpha-linoleic acid, omega-3, zinc, minerals, and the like.

  • Whole grain bread and cereals

They are rich in zinc, iron and B vitamins.

  • Carrot

Carrots, which benefit eyesight, also have a positive effect on hair health. Rich in vitamin A, it promotes the growth and division of cells, including the hair follicle.
