The first sign is an increased hair loss, visible on the pillow, when having a shower or when passing one’s hand through the hair.
This can be a transitory process due to certain diseases, nutritional deficiencies or stress situations.
If the situation continues, you will notice the following:
- Retraction of the frontal line of implantation, especially in the areas located on the temples (receding hairline), which is called Bitemporal Resection and/or clearance of the top and back of the head, towards the area called vertex or crown, in case of men.
- In women, total alopecia of a certain area never occurs, although thinning and shortening, with discoloration of midparietal hair, can happen.
- Low frontal capillary density is well distinguished in the alopecic area of the dense temporo-occipital area.
- The frontal line of implementation is always respected, although in a narrow strip. Initially, hair loss is anterior and easy to disguise, then it progresses backward and can no longer be disguised.
- Miniaturisation of the hair, which becomes fuzzier and changes its thickness and colour. The hair becomes thinner and lighter and this is called Miniature Fuzzy Hair. This hair is difficult to be seen and has a lighter aspect.
- Increase of the alopecic area following a classified pattern: Norwood-Hamilton for men and Ludwig for women according to degrees of baldness.
- Alopecia is a continuous and progressive situation with an annual loss of approximately 5%.
- Baldness beginning at an early age (around 20 year-old) will probably be a progressive alopecia, with faster and more extensive hair loss leading to miniaturisation, lightening and follicular atrophy.
