Ice point hair removal refers to the use of laser to keep the hair follicle at a certain temperature, weakening or eliminating the activity of the hair follicle as well as the surrounding stem cells, so as to achieve the effect of permanent hair removal. If the ice point hair removal 10 times or long hair, may be due to each treatment time interval is too long, or estrogen secretion abnormal cause hair growth and other reasons. 1, treatment time interval is too long: due to the hair growth cycle, usually need 3-5 times or more treatment to achieve the effect of permanent hair removal. If the interval between each treatment is too long, it may lead to incomplete treatment of the hair follicles in the growth period, thus making the hairs grow again. When dealing with again, attention should be paid to the interval time for ice point hair removal as directed by the doctor; 2, abnormal estrogen secretion: when estrogen secretion is too strong, it will easily lead to higher hair follicle activity, which in turn will not be easily eliminated by the laser, making the hair easy to grow. Such patients can go to the hospital to check the hormone secretion, if there are endocrine system abnormalities, need timely treatment; 3, other reasons: the treatment operator’s technique, skills, and the frequency of the instrument will also affect the effect of ice-dot hair removal. If there are missed parts during the operation, resulting in some hair follicles not being completely inactivated by the laser, or failing to understand the previous treatment clearly during the next treatment, it may reduce the effect of ice-dot hair removal, thus causing the hair to grow again after multiple hair removal. In addition, if you shave frequently or use irritating lotion to clean during hair removal, it may also stimulate hair growth. Therefore, you need to pay attention to choose a regular hospital or beauty institution, and at the same time, actively communicate with the attending physician and follow the medical advice to receive treatment.
