there r some great products by paul mitchell and citrus shine. but even some normal hairspray from finesse or something could work too.
hairspray- at night shower and shampoo with a volumizing product. towel dry and comb as usual. take a bit of mousse or a light hairspray and lather into roots. brush your hair out. tussle it so it isnt flattened all together. pull half of it up into a clip or elastic. take the bottom parts by about 1 inch peices or less and blast with firm hold hairspry. scrunh over and over. repeat until u have covered ur entire head u should have used1/4 to 1/2 of the bottle
(yes i no, alot of products, but alot of results!!!) sleep on it and repeat in a muchhhhhhh lighter fashion during the morning. mist all over with a gloss or a light misty hairspray. to remove, shower with a heavy conditioner. if that doesnt work, leave in for 5 hours with a cap on top. if that still doesnt work, put mayonnaise (yes, i just said mayo!) in a thick layer all over your hair. cover and let sit overnight. rinse.
for a more natural look- mousse:
agaain shower with volumizing products. coomb as usual. spritz all through w/ a heat protector and scruncha handful of mousse through ur hair. flip ur head down and blowdry with ur fingers.flip up. after this step, if u need to brush it, use ur fingers covered in mousse NEVER WITH A BRUSH OR COMB!!!!! apply some more mousse and scrunch.
to remove- rinse out with strong shampoo
thi method works ok for max 3 hrs. if u need it longer than that use above!!! ok again wash with volumizing products at night. make two frnch bradis with a middle or side part depending how u want it to be the next day. sleep on it. when u wake up, mist with a lite hairspray. remove from braids and tussle, but do not brush!!! scrunch a little bit of mousse throughout hair.
VOILA! 3 methods to wavy/ curly hair
***btw, this also works with thick hair!!!! (just dont use volumizing products and dont flip ur hair down when blowdrying!!!)
hope this helps u out!!!
