Regular trims are often hailed as essential for healthy hair, but do they actually speed up growth? Dermatologist Dr Aamna Adel, founder of Rhute Hair, dispels the myth: “Cutting the hair does not affect the follicle, which is where growth actually happens, beneath the scalp.” She explains that scissors work on the ends while growth occurs at the root, so the two are not connected. Hair grows at an average of roughly a centimetre a month, regardless of trimming frequency.
The misconception likely stems from the visual benefits of trimming. Dr Adel notes that regular trims remove split ends and breakage, leaving hair in better condition and appearing healthier and thicker, which can give the impression of faster growth. Cosmetic dermatologist Michele Green agrees, adding that taking better care of hair, including regular trims, can indirectly support healthy growth.
While trims do not accelerate growth, they prevent damage that could slow it down. Celebrity colourist Min Kim explains that regular haircuts are important for removing split ends and preventing them from travelling up the hair shaft, which can lead to further damage and breakage. Shelly Aguirre, a hairstylist at Maxine Salon, adds that salon visits allow stylists to assess overall hair and scalp health, spotting issues like buildup that might otherwise go unnoticed.
How often should you cut your hair? Dr Adel advises that it depends on the condition of your hair rather than growth itself. For most people, a trim every eight to twelve weeks is reasonable, but those with damaged, colour-treated, or chemically processed hair may need more frequent trims to prevent breakage. Curly hair, which is naturally drier and more prone to split ends, can also benefit from more regular cuts.
For those aiming to grow their hair longer, skipping cuts for months is counterproductive. Aguirre recommends haircuts every three months to maintain shape and control split ends. As Dr Adel summarises, the goal is to keep ends healthy so you are not constantly losing length to breakage.
