Val .. I understand your concerns regarding density...which is why I suggested a webcam consultation with Debbie to put your mind at rest... you will need to sit near a window [for good natural light] and she`ll give you the correct advice... your situation is a little unusual [density/colour] - there is only so much info / `idea` pics can give so that people can advise you as best they can .... it would be a shame to receive a system --especially your first-- and find it`s not fit for purpose... if you find it`s not as dense as you want, it will have to be sent back for more hair to be added [obviously delaying you from wearing ]....when John say`s 4-6 he`s talking days .. no one leaves a bond in place for for 4-6 weeks.....about a week would be the best for scalp-cleanliness/health etc. In view of your [understandable ] concerns, I`d really book that with Debbie...she`s very knowledgeable and helpful...regards, Paul.
