As the other guys have said...send in a sample of your hair for a proper colour-match. If you want to re-create the style in pic 1, I think you should order a density which is on the high side,at least 70%..... you are still young so you can carry that density easily too. Send in that pic with your order to give a better idea to the maker of how you`d like it to be. Make a template of your thin area for a good fit. If you can post a pic of your remaining hair, it would help to give more accurate advice as to the density you need to order. Regards, Paul.
