Wash hair loss areas before use_x000D_2. Spray the hair loss solution on the affected area, rub it repeatedly for 10-20 minutes, and then put the hair loss helmet on the head to illuminate the affected area_x000D_3. To prevent the helmet from getting dirty, put a clear membrane between the scalp and the helmet (e.g. plastic wrap). Features: 1The wavelength of luminescence is 630?660 nm. After red light irradiation, catalase activity of mitochondria increases, cell metabolism and protein synthesis are enhanced, local blood circulation is promoted. 2Contains 186pcs irradiation points, scientific average distribution of light source, all cover the scalp, the head emission wavelength is accurate, give hair follicle more powerful energy, achieve the hair growth effect. 3High energy, can regulate oil secretion, enhance and improve the blood circulation of hair follicle and new age, help hair growth, control oil and prevent hair loss, contribute for hair growth effect. 4No UV, adjustable brightness, stepless dimming, multi?stage dimming, care scalp, create a good hair growth environment. 5Generally 2?3 times per day, 7 days for a course of treatment, 3?4 days per week, 20?30 minutes each time.
