Preparing for the procedure
First of all, you need to consult a doctor to identify the cause of the hair problem and possible contraindications. At the same time, the specialist can give individual recommendations on preparation, including even examinations and tests.
If the procedure is not contraindicated, you need to give up alcohol and smoking a few days before (and it is better to do so for a long time or forever, since they have a very negative effect on the condition of your hair and health in general), salty foods, large amounts of sweets, and soda. It is better to include healthy fats (avocado, nuts, fish), fiber and vitamins (vegetables, fruits, greens), clean still water (at least 2 liters per day) in your diet.
The day before or on the day of the procedure, wash your hair thoroughly. Do not apply masks or leave-in products, do not use irons.
