Learn Spanish (Latin America): Si uso el secador, las capitas se verán muy bonitas. - If I use the hairdryer, the little layers will look very pretty.

Capitas is the diminutive of capas (layers). While it can mean the layers of hair are physically short, adding -itas here is mostly pragmatic. It softens the statement and makes the hairstyle sound cuter, more flattering, or more delicate.

Why use the reflexive se verán instead of just verán?

The non-reflexive verb ver means to see. When you want to express how someone or something looks or appears, you must use the reflexive form verse. Here, se verán means they will look, whereas verán would mean they will see.

Why is the present tense uso used when the action is happening in the future?

In Spanish, when you set up a likely condition using si (if), the verb immediately following si is always in the present tense, even if the result (se verán) is in the future tense. You can never use the future tense right after si.
