What is the best way to reduce frizz in curly or wavy/curly hair without making it look flat and lifeless (no blow drying, no straightening)?

Reducing frizz in curly or wavy/curly hair while maintaining volume and definition can be achieved through several methods:

1. Conditioning: Use a moisturizing conditioner designed for curly hair to keep it hydrated and reduce frizz. Leave-in conditioners can be particularly effective.
2. Avoiding Harsh Shampoos: Use sulfate-free or gentle shampoos to prevent stripping natural oils from your hair, which can lead to frizz.
3. Applying Hair Oil or Serum: Apply a small amount of hair oil or serum to damp hair to lock in moisture and smooth the hair cuticle, reducing frizz.
4. Using a Wide-Tooth Comb or Fingers: Instead of brushing, which can cause frizz, use a wide-tooth comb or your fingers to detangle hair gently when wet.
5. Plopping or Microfiber Towel Drying: After washing, gently squeeze excess water out with a microfiber towel or use the plopping method (wrapping hair in a cloth or T-shirt) to dry curls without causing frizz.
6. Styling with Curl Enhancing Products: Use curl-enhancing creams, gels, or mousses designed for curly hair to define curls and control frizz.
7. Air Drying: Allow your hair to air dry instead of using heat styling tools. If you need to speed up drying, use a diffuser on a low heat setting to maintain volume and reduce frizz.
8. Sleeping on Silk or Satin Pillowcases: These materials reduce friction and help prevent frizz caused by cotton pillowcases.
9. Regular Trims: Keeping your hair trimmed regularly helps prevent split ends, which can contribute to frizz.

By incorporating these methods into your hair care routine, you can effectively reduce frizz in curly or wavy/curly hair while maintaining its natural volume and bounce.
