Hey im texturized, you can see what my hair looks like in my album. IMO you have 2 options:
I would suggest that you wait 2 weeks then try again, IF you cannot easily differentiate
the processed hair fron your natural hair. Why 2 weeks? (btw do protein deep conditions during this period) because you dont want to wait until there is too much new growth...that would make it alot more difficult when it comes to timing the process. Although the hair is underprocessed, it is still processed to some degree, your new growth would be completely natural. If you wait until you have alot of new growth you run the risk of 1. overprocessing
the already processed hair or 2. underprocessing
your new growth again thus continuing the cycle of doing correctives.
Wait 4-6 weeks IF you can easily identify
your new growth from the processed hair,like this ^^^^~~~~~
For this process you would coat the processed hair with conditioner or oils or grease and then apply the relaxer. From root to tip. btw are your ends relaxed bone straight? if they are then you would apply from root to the line of demarcation...not on relaxed hair.
For either process I suggest that you gather your shed hair and experiment with the relaxer timing how long it take for you to get the desired curl pattern (if you have very different textures on you head, be sure to get hair of each pattern). Make sure your rinse the relaxer from the strands and wait for them to dry before determining the processing time to use. Also, if it takes you a long time to apply the relaxer to your hair (not smoothing ofcourse) then you should do it section by section, washing the relaxer out of one section before going to the other. This ensures that you acheive a more or less uniform curl pattern. I was being lazy the last time I texturized and I didnt do this...I just took relaxer and passed it through my hair after putting conditioner on my ends, I didnt even section the hair into quarters..needless to say I got a few straight pieces to the front of my hair (the length) and underprocessed roots
So dont be lazy like me, time it like a science
Sorry for the long post...
