split ends tend to happen if u have longer hair. make sure ur washing ur hair properly. shampoo shld only be placed on ur scalp, never past it. as for conditioner, make sure ur leaving it in for around 5 mins! i usually use that time to wash my body and then wash off the conditioner. if u blow dry ur hair make sure u only dry until itβs slightly damp to prevent heat damage and when using hair tools donβt forget to apply heat protectant! it wld help if u wore a bonnet to sleep to keep ur hair extra protected. donβt forget to brush ur hair as soon as u wake up and after showering/before bed (i usually shower before bed). i used to have longgggg hair and wld have minimal split ends :)
Your choice, or can be based on your hair type. Both are used for different tings, serums are for shines/heat/fizzy hair control while conditioners are to moisturize and for daily maintenance.
For the products, I only use hair serums so I can only recommend those which are: the standard Streax serum, Mise en Scene, Vitress, and Human Nature's hair oil/serum.

Someone plss tell me how do I get rid of spilt ends? I trimmed it but still no use it keeps on growing
