The wavy hair underneath adds a soft touch to the edgy buns. It is a fun, “cool-girl” hairstyle that photographs incredibly well.

It works exceptionally well with minimalist, modern dresses. This style is sleek, bold, and very “New York Fashion Week.”

This adds a lot of visual detail to the back of your head. It is a sophisticated way to manage wavy shoulder-length hair.

The remaining hair stays loose and bouncy. This style is delicate and works well with almost any dress neckline.

How do I keep my waves from falling out during prom?

Use a high-quality setting spray before you leave the house. Avoid touching your hair too much throughout the night to prevent oils from weighing it down.

Is shoulder-length hair long enough for an updo?

Yes, shoulder-length hair is very versatile for low buns and twists. You can also use “faux” techniques to make it look like a full updo.

What products are best for wavy hair for a formal event?

A lightweight mousse helps define waves without making them crunchy. A shine spray is also essential for that “red carpet” glow in photos.

Can I do these styles myself at home?

Most of these styles, like the sparkly slides or the ribbon ponytail, are very DIY-friendly. Practice a few times before the actual night to build confidence.

Should I wash my hair on the day of prom?

Usually, “second-day hair” holds styles and braids much better. If your hair is too clean, it might be too slippery for pins and elastics to stay.

How do I choose the right style for my dress?

If your dress has a lot of detail on the back, choose an updo or side-swept look. For strapless dresses, loose waves help frame your shoulders beautifully.
