Myth 2: Frequent Trims Make Hair Grow Faster
Truth: Trimming your hair ends does not affect your scalp follicles. However, getting your hair trimmed every six to eight weeks can prevent split ends. Regular trimming also stops the split ends from creeping further up the hair.
According to a study by The Trichological Society, hair usually grows between 0.5 and 1.7cm per month, depending on ethnicity. Your genetics, gender, age, and food habits (nutrition) are the key factors influencing your hair growth.
Even seasons can affect your hair growth. In summer, your hair grows faster (due to enhanced blood circulation to the skin and scalp), while in cold weather your body diverts blood flow to internal organs to maintain body temperature. That can slow down hair growth.
