Biotevit is a supplement taken as a course rather than a permanent part of the diet. There are several situations in which adding it to your diet seems reasonable:
- Hair has started to look duller or more brittle. This may be related to a lack of micronutrients — especially if your diet has recently been monotonous or restricted.
- Dietary restrictions. A vegetarian or vegan diet, strict diets and food intolerances can all reduce the intake of biotin, zinc and B vitamins from ordinary food.
- A stressful period. Under heavy physical or emotional strain, the need for B vitamins may increase, and the diet often becomes less balanced.
- Seasonal changes. In autumn and winter many people notice that their hair and nails look worse — partly due to changes in diet and lower activity.
Bear in mind, though, that the result depends not only on the supplement but also on your general health, stress levels, sleep quality and diet as a whole. If changes in the appearance of your hair are marked or long-lasting, it is better to consult a specialist first — the causes can vary.
