Hair not only reflects your external health, but is also influenced by what you eat. Many people see shampoo and treatments as the solution to damaged hair, but an important factor is diet. Some foods can actually weaken the hair and cause further problems. Here we go over what you should avoid to protect your hair — and how PRP can help repair and strengthen it.

Foods that can harm your hair

By avoiding these potentially harmful foods, you can give your hair a better chance to recover and grow stronger.

Sugar

A high sugar intake can lead to inflammation in the body, which can negatively affect the hair follicles and cause hair loss and brittle hair.

Fast food and deep-fried foods

Oily and oily foods can clog pores, even on the scalp, which can interfere with hair growth and create imbalance on the scalp.

Too much dairy products

An excess of dairy products can, in some people, trigger an overproduction of sebum, which can lead to an oily scalp and hair loss.

Alcohol

Alcohol can cause dehydration, which affects both the scalp and hair. Dehydrated hair is more prone to break off and get damaged.

Caffeine in large quantities

Although moderate amounts of coffee do not harm, overconsumption can lead to increased stress and dehydration, which negatively affects the health of the hair.

Foods that strengthen your hair

To complement a healthy hair care routine, it is equally important to include nutritious foods in your diet:

  • Oily fish (eg salmon and mackerel): Rich in omega-3 fatty acids that strengthen hair follicles.
  • Green leafy vegetables: Full of iron and vitamin A, which contributes to a healthy scalp.
  • Eggs: Contains biotin and protein, which are key ingredients for building stronger hairs.
  • Nuts and seeds: Rich in zinc and vitamin E, which contribute to healthier hair and reduce hair loss.

PRP — A powerful hair care for damaged hair

What hair care is available for damaged hair? Although diet plays an important role in hair health, modern treatments such as PRP (Platelet-Rich Plasma) provide extra support. If you have severely damaged hair or suffer from hair loss, PRP is an innovative hair care method that works in depth to strengthen and repair hair follicles.

A blood sample is taken and processed to extract nutrient-rich plasma, which is then injected into the scalp to strengthen hair follicles and activate dormant hair growth.

We review your needs and tailor a treatment that suits you — be it PRP or other solutions.
