1. Observation: Straightened hair presents a vertical hairstyle, like a waterfall, and you can hardly find any curved hair. Softened hair presents a more natural and supple effect, which is brighter than that after straightening.

2. Touch: Wrap your fingers around your hair. If there is no trace of hair after winding, it means that the hair is dry. If there are obvious marks after winding, your hair is still wet.

3. Pulling hair: Straighten a small bundle of hair. If your hair doesn't break after straightening, it means your hair is dry. If the hair is broken after straightening, it means that the hair is still wet.

The above is the way to judge straightening and softening, and I hope it can help you.
