Phase I: Shows an adolescent hairline, usually located on the upper brow crease. There is no hair loss in the hairline or the crown of the head.
Stage II: Shows the progression to a mature hairline, which is slightly above the upper brow crease. Hair loss at this stage very mild and mostly concentrated at the front hairline.
Stage III: Is the earliest stage of hair loss considered cosmetically significant enough to be called “baldness” based on this scale. At this stage, most men show a symmetrical deep recession at the temples, which are either bare or only sparsely covered with hair. The vertex figure shows there are additional thinning of the hair at the crown of the head.
Stage IV: Comprising a deeper recession at the front of the head in the temple areas. Hair loss at the crown often proves to be a bridge of lower density will separate its loss of hair at the front of the scalp of those at the top or crown. The sides of the head are generally well covered with hair.
Stage V: Marks the beginning of severe hair loss. While there is still a small separation between the loss of hair at the hairline and hair loss on the crown, the hair band between them is much thinner and narrower. Hair loss, both the crown and the temporal areas larger and clearer.
Stage VI: The bridge of hair that once separated the front of the head of the crown is almost completely lost, remain only a few small strands. The remaining hairs now forms a horseshoe shape around the baldness concentrated in the center of the scalp. Hair loss will further extend on the sides of the cup at this stage.
Stage VII: The most advanced stage of hair loss, only a thin crown of hair remains on the sides and back of the scalp.
