Please do an intensive oil treatment at home… mix Coconut oil + Olive oil and heat it in a tadka pan. Add sliced onions + Curry leaves + black jeera to this oil mix and bring to boil till the onions start browning. Turn off the stove and strain the oil. Allow it to cool till lukewarm and apply from scalp to tips. Cover with a shower cap and let this stay for 45 mins to an hour. If you don’t want an oily scalp then don’t over apply. Shampoo with a gentle shampoo and apply a hair mask (any) + condition.
