Keratin Treatment in Princeton & West Windsor Township, NJ

A keratin treatment is a smoothing treatment that reduces frizz and cuts down daily styling time, and it's specifically useful in central New Jersey, where summer humidity is one of the biggest complaints clients bring to their first appointment.

Metro offers both a full keratin treatment for longer-lasting smoothing and a Silky Smooth Mini Keratin Treatment for clients who want frizz control without the full processing time or cost — Dawn can help you pick the right one at booking or consultation based on your hair and goals.

Frequently Asked Questions

How long does a keratin treatment actually last in New Jersey humidity?

Results vary by hair type and how it's cared for afterward, but a full keratin treatment generally outlasts styling products alone through the humid months — Dawn can set realistic expectations based on your specific hair.

What's the difference between the full treatment and the mini version?

The mini keratin treatment is a shorter, lighter-processing option for frizz control and smoothing touch-ups; the full treatment is a longer-lasting, more intensive smoothing service.

Can I wash my hair right after a keratin treatment?

There's typically a waiting period before the first wash — Dawn will give you exact aftercare timing and product recommendations after your appointment.
