I read this once from a top HT surgeon: Hair is deliberately transplanted at lower than naturally-occurring densities and so we depend on some illusion to make it look fuller than it actually is. Transplanted hair will always look fuller when 2-3 inches long, dry, separated, and styled to layer like shingles on a roof. It will always look thinner when cut short, spiked up, parted through, wet or clumped with product.
