One, your shampoo is too drying. And you are not washing
right, or you are using too strong a dandruff shampoo.
Two, I dont read you using a conditioner.
three, that gel does not moisturise.
four, your growth hormones or your change in diet might be
affecting your hair.
Answer One, Change the shampoo, maybe a moisturing anti dandruff
shampoo and have another moisturing cleansing shampoo for weekends.
Massage your head when shampooing, meaning you use the pads of your
fingertips to massage your scalp rubbing the shampoo onto yuor
scalp and rinse well.
Answer two, apply conditioners, dont apply in globs onto your
scalp. just make sure your fingers have conditioner and run
those fingers thru the hair, avoiding your top and your scalp.
Three, get moisturing serum, apply them to the hair and then the
gel to scuplt. Not too much, a bit of wind blown hair wont
look that bad.
Answer four, you need to take more green vegies and maybe some
supplements.
A suggestion: Get those Garnier hair colour and dye your
hair. their moisturing ingredients helps to condition hair
and thus staightening your fizzy strands. your other
alternative is to apply your own hair mask or go for treatments at
salons.
