Make sure you trim the ends every 6-8 weeks to prevent split ends, as these damaged ends can travel up the hair shaft and cause frizziness.  

If you want to keep your hair healthy, ensure protection from heat and reduce the use of hair styling tools that apply heat to the hair. 

Try using gentle and moisturising shampoo and conditioner. Dry hair leads to split ends and frizz. Also, incorporate oiling into your haircare routine. 

Chemical treatments like bleaching, colouring, and perming can cause severe damage to the hair strands, leading to hair dryness and split ends.
