Rogaine is a topical hair growth treatment that has been proven effective in clinical studies; however, results vary from person to person. Genetic factors and extent of hair loss both play a role in the effectiveness of Rogaine.
Clinical studies of Rogaine use in both men and women have shown positive results. Due to the fact that results vary from person to person, it is recommended to use the treatment twice a day for at least four months in order to determine its effectiveness.
Rogaine is not considered a permanent cure for hair loss. Continual use of the product is recommended for optimal results as discontinued use of two months or longer can lead to shedding of new hair growth. Rogaine has been proven less effective for individuals with thinning hair close to the hairline and individuals with genetic pattern baldness. Additionally, individuals in the early stages of baldness tend to achieve better results than older individuals with long-standing hair loss.
Side effects of Rogaine include scalp irritation, dryness and itching; however, side effects tend to be mild, if experienced at all. In a study of 6,000 men and women using Rogaine, only 7 percent of the individuals in the study reported adverse reactions.
