Over the years I have slowly switched to paraban free sulphate free shampoo to avoid stripping my hair of its natural oils. I do not blow dry unless absolutely necessary like maybe 2 - 3 times year , if I do then it is usually in cold setting. I also do not use hair products or setting sprays . Over the years I have figured natural ways of curling my hair by scrunching or over conditioning if I want it straight.
I swear by coconut oil (virgin). It does wonders for your hair and skin. I use Schwarzkopf moisture kick spray to keep it moisturised during those hot summer days when hair tends to dry out in the sun.
For those who gym and feel the need to wash your hair often , give your hair plain water baths and limit shampooing to twice a week.
Organic argan oil which is readily available in the US , is my split end and dry end saviour (apart from regular split end trimming). Just a few drops applied to hair ends regularly. It is not too oily so u can go out with it.
I also use the occasional curd and lime mixture on my hair which keeps dandruff at bay.
For those who use a lot of hair products I advise the use of clarifying shampoo once a month to break down the chemical build up on hair.
Last thing is stimulating hair massages - love em.
The only chemical abuse my hair goes through is hair colour once a year - but I also try to follow it up with good hair care which includes weekly conditioning at home and weekly oil massages at the salon...
