Hair contrast, hair length, hairstyle and hair character are the most important aesthetic principles in hair restoration to achieve a natural look. Naturalness is more important than density, but density can be achieved when adhering to the simple aesthetic principles.
Low Contrast or “hair to scalp color ratio” is extremely important in understanding aesthetic density. Low contrast would be “less extreme hair to scalp ratio” i.e. lighter hair on light scalp verses darker hair on light scalp.
Below is a perfect example of changing hair color from high contrast to low contrast creates the illusion of increased aesthetic density. This patient also had two sessions of non-surgical Amniotic Cell/ CRP/Matrix injections.
Hair length is critical with aesthetic density. The same numbers of hair’s an inch shorter would look 50% less dense.
Below (Fig 3) is a patient who had one Follicular Unit Extraction (FUE) hair transplant for his crown. He had fine straight dark colored brown hair and was wearing it short. After one session of FUE, eleven months later he 1) let his hair grow longer, and 2) hair color go natural (lower contrast) this is his result.
Hairstyle when hair is parted on the side it has more aesthetic density than when combed back, combed forward or parted in the middle. The patient below in Fig 4 had one Stem Cell Assisted FUT hair transplant procedure and is now parting his hair. Since he has more hair and more actual density his hairstyle allows him to increase the color contrast.
Hair Character is characterized as fine, medium or coarse, straight, wavy or curly. Denser curlier hair will look thicker than fine straight hair, but fine straight hair may look more natural if restored. Fig 5 below is an example of a Stem Cell
Fig 6 below is an example of fine hair after a Stem Cell Assisted FUT, very natural! Obviously, the injections of the stem cells with the permanent transplant created a denser more natural result.
