Relaxers, Straighteners, Conditioners

Seeking recommendations for

• volume-retaining curl relaxer home kits;
• straightener rods; and
• leave-in conditioners, serums, humidity-resistant products;

keywords: "inexpensive" and "available locally," e.g., from venders such as Wal-Mart, Cost Cutters, Walgreen's, etc.

Hair Type: Thin, daily combined loss of yarn-thickness; simultaneously course and smooth in texture, depending on the area; repeatedly colored (originally "mousy"), both salon and home applications; "naturally frizzy," lately a combination of limp and lifeless paired with patches of curl--extremely temperamental; medium length, desired longer...thicker, healthier, straighter, manageable.
