Keratin Treatment

Temporary smoothing for less frizz, more shine and easier styling.

A keratin treatment is a temporary smoothing service that cuts frizz and adds strength and shine, so your hair dries smoother and styles faster. The Collage Salon offers a keratin smoothing treatment, an express keratin treatment and an express keratin add-on in Belltown, Seattle. Your natural texture slowly returns as the treatment wears off.

Who is a keratin treatment for?

Keratin is for hair that frizzes, puffs or fights you every morning. It suits wavy and curly hair that you mostly wear smooth, and straighter hair that turns fuzzy the moment it meets damp Seattle air. It is also a good fit if blow drying feels endless and you want an easier routine.

Because it is temporary, keratin is a lower-commitment way to try smoother hair. It softens frizz rather than wiping out your texture for good, and it fades gradually instead of leaving a hard line at the root as your hair grows.

The express options make it easier to fit in. Not everyone has room in the week for a longer visit, and smoothing should not be reserved for people with open calendars. The express keratin treatment is designed for busy schedules, and the express add-on can join another hair service you already have booked.

What happens at your keratin treatment appointment

  • 1. Consultation

    Your stylist asks how you style your hair now, how much frizz you deal with and what you want to change. They look at your texture, condition and recent color. Then they help you choose between the full keratin smoothing treatment and the express option based on your hair and your schedule.

  • 2. Cleansing

    Your hair is shampooed with a clarifying wash to clear away product, oil and buildup, since clean hair takes the treatment more evenly. Your stylist then dries your hair so it is ready for the smoothing formula and every strand can absorb it.

  • 3. Applying the treatment

    Your stylist works the keratin formula through your hair in thin sections, from near the root to the ends, keeping it off the scalp. Even coverage matters, because missed spots will stay frizzy while the rest is smooth. The formula then sits on your hair so it can absorb.

  • 4. Blow dry and flat iron

    Your stylist blow dries your hair smooth and then passes a flat iron over small sections. The heat helps seal the treatment into the hair. You leave with sleek, shiny hair and clear advice on washing, styling and caring for your smoothing at home.

How do you care for a keratin treatment?

Ask your stylist how soon you can wash after your appointment, since timing can vary with the formula. When you do wash, use a gentle shampoo and conditioner. Harsh, clarifying shampoos strip the treatment faster, so save those for when you want it to fade.

Keep heat styling light. Your hair should air dry smoother than before, and a quick blow dry will usually finish it. Chlorine and salt water can shorten the life of the treatment, so rinse with clean water before and after a swim.

For product advice, ask your stylist. The salon carries Oribe, Kevin Murphy, La Biosthetique and Hairstory, and your stylist can point you to what suits smoothed hair.

Full keratin treatment or express: which should you book?

The full keratin smoothing treatment is the deeper option. It suits thick, frizzy or very textured hair and anyone who wants the most smoothing from one visit.

The express keratin treatment is designed for busy schedules. It gives a lighter dose of smoothing and shine, which works well for hair that is only a little frizzy, or as a first try. The express add-on goes a step further in convenience, since you can add it to another hair service you already have booked.

If you cannot decide, describe your mornings to your stylist. How much effort you spend fighting frizz is often the best clue to which option will make the biggest difference for you.

How does keratin compare with a Brazilian Blowout or Japanese straightening?

All three smooth the hair, but they differ in strength and permanence. A keratin treatment is temporary and gradually washes out. A Brazilian Blowout is also a smoothing treatment, aimed at dry, damaged or chemically treated hair. Japanese hair straightening is permanent: treated hair stays straight, and only new growth comes in with your natural texture.

If you want to keep the option of wearing your waves, or you are trying smoothing for the first time, a temporary service makes sense. If you want straight hair for good and your hair is healthy enough, ask about Japanese straightening.

Frequently Asked Questions

Can I get a keratin treatment on color-treated hair?

Usually, yes. Many people get keratin on colored or highlighted hair. It is often best to color first and smooth afterward, since the treatment can affect how color takes. Tell your stylist about your latest color service and any lightener, and they will plan the order that works for your hair.

Will a keratin treatment make my hair completely straight?

Not usually. Keratin is about smoothing, not flattening. Frizz drops, shine goes up and your hair is easier to blow dry straight, but most waves and curls soften rather than vanish. If you want hair that stays straight with no styling, Japanese straightening is the permanent option to ask about.

Can I get keratin while pregnant or breastfeeding?

This is a question for your doctor. Smoothing treatments involve chemicals and heat, and only your doctor can advise on your situation. Check with them first, then tell your stylist when you book so they can talk through your options with you.

Can I tie my hair up after a keratin treatment?

Ask your stylist before you leave. Some formulas need your hair to stay loose and untouched for a while so bends do not set in. Others are more flexible. When ties are fine again, choose soft scrunchies or claw clips over tight elastics, which can leave dents in smoothed hair.

Does keratin help with humidity and rain?

That is one of the main reasons people book it. Damp air makes the outer layer of the hair swell and frizz. A keratin treatment smooths that layer so your hair holds a sleek finish longer in wet weather. It will not make your hair waterproof, but your blowouts should hold up better in drizzle.
