Hi, i had the grainy like things on my scalp too...with itchy bumps... my hair began to fall out... ...( i know it's not lice...as a hair dresser i know what they look like) and i had terrible acne... I have had acne for years that seemed to get worse...the painfull kind that makes you not want to leave the house... (I eat healthy, drink lots of water, take lots of vitamins, excercise, have good hygine, good housekeeping habits... and I am 27 years old... I don't smoke, I don't drink...and i am still affected... no one else in my family has this problem, not even my guy who shares pillows or my daughters who have used my brushes...) you might want to look into something called the ***demodex mite***... they live on the face/head of most adults... come out at night...and thrive in people that have weakened immune systems...(i was on antibiotics for months for lyme disease...it wreaked havoc on mine) it seems tea tree oil helps... also sulfur based products (i use bye bye blemish) and sun light... i also have a doctor that thinks i'm crazy... and won't perscribe the meds i need... so i'm looking for a new one... I hope this helps...
THE DEMODEX MITE IS MY ENEMY...AND MAY VERY WELL BE YOURS...
This could more likely seborrhoeic dermatitis. It is a skin disorder affecting the scalp, face, and trunk causing scaly, flaky, itchy, red skin. It particularly affects the sebum-gland rich areas of skin.
Side effects to inflammation may include temporary hair loss. If severe outbreaks are untreated for extended intervals, permanent hair loss may result, because of damage to hair follicles.
Soaps and detergents such as sodium laureate sulfate may precipitate a flare-up, as they strip moisture from the top layers of the skin, and the drying property of these can cause flare-ups and may worsen the condition. Accordingly a suitable alternative should be used instead.
Among dermatologist recommended treatments are shampoos containing coal tar, ciclopiroxolamine, ketoconazole, selenium sulfide, or zinc pyrithione. For severe disease, keratolytics such as salicylic acid or coal tar preparations may be used to remove dense scale. Topical terbinafine solution (1%) has also been shown to be effective in the treatment of scalp seborrhoea,as may lotions containing alpha hydroxy acids or corticosteroids (such as fluocinolone acetonide). Pimecrolimus topical lotion is also sometimes prescribed.
It would be advisable to consult a skin specialist for your symptoms and a proper clinical examination if your symptoms persist.

But Doctor, doesn't seborrhoeic dermatitis cause flakes? I have been reading post after post of ppl with this same problem I have, and we have crystalized-like grains of sand (sugar or salt). Not flakes.
Please see my profile which decribes my condition in full. I have not seen one post that answers the issue and includes grains rather than flakes as a symptom!
