research Clinicopathological insights into the phenotypic variation of autosomal recessive hypotrichosis/wooly hair by c.736T>A LIPH mutation
The conclusion is that the variation in hair thinness in patients is mostly due to the amount of underdeveloped hairs, and treatments that thicken fine hairs might work for those with mild to severe conditions.
