Hair loss is not usually anything to be worried about, but occasionally it can be a sign of a medical condition. Some types of hair loss are permanent, like male and female pattern baldness. This type of hair loss usually runs in the family.Instructions to produce various morphological hair shapes are provided by genetic signalling, and hair form gets established into the hair fibre through keratinisation [11], [113]. Hair follicles require the interplay of β-Catenin, BMP, Shh, and Wnt signals to form and continue to generate hairs in a continuous cycle [120], [121].
