Brintop Diva 2% Topical Solution should only be applied directly to the scalp area in the amount and in the way specified on the label or by your doctor. Clean and dry your scalp before using it. It may take approximately 2- 4 months before you notice any hair growth. The first growth may be soft, colorless, and barely visible. Using more than recommended will not speed up hair growth and may increase the likelihood of side effects. This medication must be used continuously to maintain hair growth. Tell your doctor if your condition does not improve or worsen after using it for 4 to 6 months.
