Unfortunately, the perfect amount of styling product that works best in your hair can only be determined through trial and error. When trying a new product, first apply a dime-sized amount to a section of hair and then observe. If it looks good, then continue applying the same amount to each section of your hair until complete. If you haven't achieved the desired effect, try increasing to a nickel-sized amount and apply to another section of hair. Compare results. If you still aren't satisfied, try increasing to a quarter-sized amount and then compare results. At this point, if it still isn't working, then maybe it isn't the right product for you. Sometimes, in cases of frizz or lack of shine, the problem is best corrected with proper cleansing and conditioning, not by over-applying a styling gel, pomade, serum, oil, or etc. Remember to always keep your expectations realistic when it comes to styling products and know that less is more.
