I noticed that my hair needs a trim, it has been a few months since I last had one. Dusting or trimming is important, this is what helps to reduce or remove split ends. Split ends can be very damaging to our hair as the split from the bottom of the hair shaft can split the hair strand all the way up to the root. Dusting regularly will ensure that the split end are kept at bay and that your hair remains healthy.
Now there isn't a time frame to trim your hair but every three months or so is recommended. Our hair is meant to be the same thickness from root to tip, when we start having thin ends that's unhealthy and should be trimmed.
Whether you have relaxed or natural hair trimming is very important for your hair. Below is a short video from Shekia Renea on how to trim natural hair.
