1. May I use anti-hair loss products during pregnancy and while breast-feeding?

No research studies in pregnant women and nursing mothers using Fitoval products have been carried out. According to the data from available studies neither the substances in capsules nor cystine are harmful. We recommend that pregnant women and nursing mothers consult their doctor before using Fitoval capsules or Fitoval anti-hair loss lotion.

2. Why do men suffer from a specific form of hair loss, the temporal-frontal loss?

Androgenetic alopecia or male pattern hair loss is one of the most common forms of hair loss. In men it usually occurs at the front hairline and in women as central thinning on the crown of the head. In most people this pattern reflects the characteristic distribution of androgen-sensitive hair follicles (male sex hormones). In people who are prone to androgenetic alopecia, androgens may, starting at puberty, begin to shorten the growth (anagen) phase and to reduce the number of follicles, which leads to hair thinning. The male hormone testosterone plays an important role. In the hair follicle cell, testosterone converts by means of the 5-alpha reductase enzyme into its biologically more active form, dihydrotestosterone (DHT). This hormone binds to androgenic receptors in the hair follicle and triggers cellular processes which shorten the hair cycle growth phase.

3. It is often said that hair loss is hereditary. Who is it inherited from?

Hereditary hair loss can be inherited from either the mother's or father's side of the family. Since several other genetic factors can play a role, it may skip a generation and reappear later.

4. My hair is thinning. Is there a way to prevent my hair loss?

There are temporary and permanent types of hair loss. Temporary hair loss may, for example, be induced by prolonged stress, insufficient nutrition, hormone changes related to pregnancy, and deficiencies in the function of the immune system. Permanent hair loss usually results from a gradual reduction in the number of active hair follicles, from permanent weakening of activity of hair follicles, or from different skin diseases.
In temporary hair loss the condition can be restored to normal by finding and eliminating the cause. Hair growth may be enhanced and promoted by adequate care, while medical treatment is necessary only in rare cases. In most cases of permanent hair loss it may be difficult or even impossible to stop the process. Medical treatment as well as adequate and proper care is required.

5. Why does dandruff occur?

Dandruff is caused by different external (lifestyle, nutrition, environmental impacts) and internal factors (immunological and neurological abnormalities, hormonal factors). Malassezia fungi are described as the key cause for its formation. In the past, the most frequently mentioned was M. furfur fungus, but new scientific findings show that the fungi most closely associated with dandruff are M. globosa and M. restricta.

6. When does dandruff most frequently occur?

Dandruff constitutes a very widespread problem, as many as 50% of the population suffer from it at some time during their life. It is more common in men than in women. It is usually first seen at the onset of puberty, mostly reaching its peak in early twenties and it often disappears after the age of 50. Children and older individuals suffer from dandruff less frequently. It seems that dandruff is seasonal: it is most severe during the winter and mildest during the summer.

7. Why does dandruff repeat in some people, while others never have it?

Dandruff occurs most frequently when conditions on the scalp are appropriate and a person is prone to this problem. Due to various factors, e.g. hormonal or digestive abnormalities and stress, the quantity and composition of sebum may change and also the pH value of skin on the scalp. Thus, favourable conditions are created for excessive fungus multiplication. Fungi break down fats in sebum, thus free fatty acids are created which cause irritation to scalp. The consequence is an accelerated cell division and increased creation of surface cells, which is noticed as excessive skin scaling and annoying scales on shoulders.

8. I suffer from severe dandruff. How often should I wash my hair, without additionally irritating my scalp?

When using anti-dandruff products, it is recommended that you follow the manufacturer's instructions, especially those concerning the frequency of hair washing, duration of anti-dandruff care or therapy and the contact time of shampoo on hair and scalp during washing.

9. What causes the greatest damage to the hair?

The most common type is mechanical damage induced by combing. Combing dry hair makes the hair cuticle thinner; however, combing wet hair causes even greater cuticle damage. A very common type of damage is due to environmental effects such as strong sun's rays, temperature differences and changes in air humidity.

10. My hair ends are badly split. Can hair care products improve this?

In severely split hair ends the most effective measure is to cut off the ends. The next best step is to use a suitable shampoo which regenerates the damaged hair surface, smoothes the surface and restores the hair's natural shine.

11. What sort of a brush or comb should I use to cause the least damage to my hair?

Combing always causes damage to hair, but unfortunately it is an indispensable part of hair care. The least damage is done by using a wide-toothed comb or a natural fibre brush.

12. What is keratin?

The hair fibre or shaft structure is composed primarily of the protein known as keratin. The hair's mechanical properties depend on the composition and organization of keratin fibres which are located in the cortex and give the hair its firmness and suppleness. Keratin is unique because it contains a large amount of cystine, an amino acid, which is rich in sulphur and which via disulfide bonds ensures a cross-linking of keratin chains, thus accounting for much of the strength and firmness of the hair.
