She should wash with a moisturizing 'poo (therappe, etc.) and do a deep penetrating moisturizing conditioner with at least 15 minutes of low heat (humectress, etc.) followed by a moisturizing leave in (headdress, giovanni, etc.). Also, "polishers" can be drying to some because of the silicones (my hair hates 'cones and I discovered that repeated use dried out my hair -- I avoid leave-ins with 'cones like the plague!). Also, sheen sprays can be drying as well becasue of alcohol content. Instead of the polisher and spray, I'd suggest a light natural oil or butter, like coconut, jojoba or olive after hair is dried. Thus:
1. wash with moisturizing shampoo (therappe, etc.)
2. deep conditioner with moisturizing conditioner (humectress, etc.) apply generously, cover with plastic cap and apply heat for at least 15 minutes. Rinse thoroughly
3. towel dry and apply moisturizing leave in (headdress, giovanni, etc.)
4. dry hair completely, preferable rollerset under hood dryer or airdry.
5. rub small amout of of butter, jojoba or olive oil in palms and apply to hair for added shine and to seal in moisture.
This routine works like a charm for my 4b relaxed hair whenever its dry. BTW, products are for suggestions only and any mositurzing 'poo, conditioner and leave-in should do the trick.
Hope this gives some ideas . . .
