The grey hair ârule of thumbâ is that by the age of 50, half of the population have lost the colour in 50% of their hair. When researchers tested this rule, they found that 74% of people aged between 45 and 65 had grey hair, with an average intensity of 27%. Generally, men have more grey hair than women.
Hair naturally begins to split around 3 months. To prevent any permanent damage from these naturally occurring split ends, you should schedule a trim with your stylist every quarter. Scheduling a trim every 3-4 months or 12-16 weeks will help to keep your hair healthy and strong. Scheduling a trim every three to four months will help maintain the shape of your style and remove naturally splitting ends. Hair grows about 1/4 to 1/2 inch a month. If ends are clipped regularly, you will only remove about 1/4 inch or less which will leave you with noticeable growth and length retention.
