It uses only natural bristles, and by mixing boar bristles with black pig bristles, UYEDA BISYODO have created a flexible hair brush. The use of 100% natural bristles helps to reduce static electricity and improve the cuticle while adding shine and strength to the hair. Brushing stimulates the blood flow to the skin and promotes healthy and beautiful hair. The handle is made of African rosewood to express the unique texture of the wood.
