i reckon it's the oil(jojoba,lavender,peppermint,t,tree) rinses and better (calmer?)attitude.
ive always liked lavender and used it for stress(aroma-therapy) but have since joining here found it is also considered excellent for thickening hair growth and stimulating scalp re-gen, so now use it in every rinse.
By my reckoning my hair started to thin 16 years ago and i've wanted dreads for 10 yrs so if id started them 10yrs ago and treated my hair this good id have brilliant dreads by now and probably more hair,lol.
