One week before, do a protein treatment, such as the Aphogee Two Minute Keratin Reconstructor. If you notice breakage, do the Aphogee Treatment for Damaged Hair instead. Do a strand test to figure out which protein treatment is best. (read SistaSlick's articles discussing strand tests). On the last 3-5 days prior to relaxing, do not scratch, comb, or wash hair. Do not do anything to disturb your scalp.
One week after, do a protein treatment, followed by a moisturizing treatment. I usually do Aphogee Treatment for Damaged Hair one week after. However, this time I may do Nexxus Emergencee instead, 'cause Aphogee is really intense.
Hope this helps.
