Hi Thanks for writing to us. To a large extent premature greying of hair and texture of hair is genetically determined. So tonsuring as such does not help in preventing greying of hair or improves hair texture. Use of a good shampoo and conditioner along with proper oiling of hair would reduce frizziness of hair to some extent. Intake of a good healthy diet, avoiding stress and smoking may be helpful in premature greying. You may also start an oral supplement rich in vitamins and minerals like calcium pantothenate and PABA. For the same, you may take Tablet PABAtab and follihair new once daily after consulting your dermatologist Hope this helped
