Oh gawsh, the only advice I could possibly give is to just let it grow naturally. I did absolutely nothing to mine for close to 2 years. All I used was leave-in Moroccan/Argon oil off and on, washed my hair with whatever we had in the shower (which is good to make your hair not so dependant or habituate on one shampoo/conditioner of a particular brand as your hair changes constantly because of the climate, your lifestyle, health changes etc), so that’s a number 1 tip! Depending on your type of hair, growing it out and not cutting it for a lengthy time can certainly militate the health of your locks, so treatments by your hairdresser or even home remedies such as leaving coconut oil in over night and washing it in the morning can help to restore that silkiness! Try finding a Sulphate-free shampoo and conditioner as the nasty chemical used in most hair products can damage your hair a considerable amount when using time and time again. I’ve only recently just started to cut my hair again and it’s growing super quick. But that’s my hair, I’m no hair dresser! Test some of those out. x
