* Trimming doesn't directly make hair grow faster from the roots. Hair growth happens at the follicles under the scalp, and trimming the ends doesn't affect these follicles.
* Trimming helps maintain healthy hair, which indirectly supports growth. Trimming removes split ends and damaged hair. If you don't trim, split ends can travel up the hair shaft, causing breakage. This breakage makes the hair appear shorter and thinner, and it can prevent you from retaining length. So, by preventing breakage, trimming helps you maintain the length you've already grown.
* Regular trims can improve the appearance of hair. By removing dry, split ends, hair looks healthier, fuller, and more even.
In Summary:
Trimming does not directly affect the rate of hair growth at the roots. However, regular trims are important for maintaining healthy hair, preventing breakage, and preserving length. This, in turn, gives the *illusion* that hair is growing faster and promotes overall hair health.
