Protect Your Investment: A Stylist's Secrets to Making Your Hair Color and Treatments Last

There's no feeling quite like walking out of the salon with fresh color or a new smoothing treatment. Your hair feels silky, the color is vibrant, and you feel unstoppable. But within hours, reality sets in: "How do I keep this looking good?"

I'm Jess LaFerrara, and I've been doing hair at The Warehouse Salon in Fairfield for six years now. That question, how to maintain your results, comes up in almost every appointment. And honestly? It took me a few years behind the chair to figure out the real answers, not just the textbook ones they taught us in beauty school.

The Hard Truth About At-Home Care

Here's what nobody tells you upfront: what happens in the 72 hours after your appointment matters more than the three hours you spent in my chair.

I learned this the hard way with a client named Thessaly back in 2021. She'd saved up for months for her first Brazilian Blowout. I did the treatment perfectly. She looked incredible walking out. Three days later, she texted me a photo. Her hair had a weird bend right at her temple, like someone had crimped it. Turns out she'd worn a headband to yoga the day after her appointment.

That treatment now had a permanent kink that would take months to grow out. When she came in next, I could feel how discouraged she was while running her fingers over that bent section, asking if there was any way to fix it immediately. There wasn't. I felt terrible. I should have been clearer about those first 72 hours.

When you get a professional service, whether it's balayage, all-over color, or a keratin treatment, we're changing your hair's structure at a microscopic level. For color, we open the cuticle to deposit pigment. For smoothing treatments, we're sealing that cuticle with keratin protein. Your hair has literally been rebuilt. It needs different care than it did before you sat in my chair.

The Critical First 72 Hours (No, Really, Don't Mess This Up)

After Thessaly's headband incident, I started being obnoxiously specific about the first three days post-treatment. If you're getting a Brazilian Blowout or keratin treatment, these rules are non-negotiable:

Don't wash your hair. Not a quick rinse. Not "just the roots." Zero water for 72 hours. The keratin needs time to fully bond to your hair strands. I've had clients text me on day two asking if 48 hours is close enough. It's not.

Keep your hair completely straight and loose. No ponytails, no clips, no headbands, no tucking it behind your ears, no sleeping with it twisted under you. Any bend can become semi-permanent while the treatment sets. My client Rhiannon learned this when she wore her hair in a low bun to a wedding on day two. She had a horizontal line across the back of her head for four months.

Stay away from water completely. If you work out and get sweaty, if it rains on you, if you somehow end up splashed, blow-dry and flat iron those sections immediately. I remember Zinnia called me panicking after getting caught in a downpour on day one. We managed to save most of the treatment by having her come back to the salon so I could dry and straighten everything properly, but it was close.

Living in Essex County with our humid summers makes this particularly challenging. I usually tell clients to schedule their smoothing treatments for a week when they can lay low, no gym, no outdoor plans, nothing that involves sweating or getting wet.

The Washing Mistake Almost Everyone Makes

Once you're past the initial 72 hours, the biggest threat to your color or treatment is over-washing.

Most people wash their hair five to seven times a week. That's way, way too much for treated hair. Every time water hits your hair, the cuticle swells and opens slightly, letting color molecules and treatment escape. It's gradual, but it's constant.

I try to get my color clients down to two or three washes per week. My client Eponine pushed back hard on this at first when she felt gross with "dirty" hair. I had her try it for one month. Her balayage, which usually needed refreshing at six weeks, still looked vibrant at ten weeks. When she came in, she kept touching her hair, almost surprised that it still felt smooth and the color still caught the light the way it had when it was fresh. She texted me later: "Okay, you were right, I'm a convert."

Dry shampoo becomes essential. But I learned this the hard way too: not all dry shampoos work the same. The cheap stuff leaves this chalky white residue that's impossible to brush out on darker hair. I had a brunette client named Azura who looked like she'd been dusted with flour every time she used drugstore dry shampoo. We switched her to a professional one and the difference was night and day.

The Sulfate Situation (This Is Where People Lose Me)

If there's one thing I sound like a broken record about, it's sulfates. I get it because I lose people here. "It's just shampoo, how much can it matter?"

A lot. It matters a shocking amount.

Sulfates are the detergents that create that big, satisfying lather in regular shampoos. They strip everything from your hair, oil, dirt, and also every bit of color and keratin we just spent hours putting in there. Using a sulfate shampoo on colored or treated hair is like taking a nice painting and scrubbing it with dish soap.

I used to recommend sulfate-free shampoos in kind of a casual way, like it was a nice-to-have. Then I had a client named Marlowe who was getting full highlights every six weeks. Her color would look dull and brassy within two weeks, every single time. I couldn't figure it out. Finally, I asked her to bring in her shampoo. It was loaded with sulfates which are basically liquid detergent.

I got her onto a sulfate-free formula. Her highlights started lasting eight weeks. The difference wasn't just visual because when I touched her hair at her next appointment, it felt completely different. Smooth, sealed, hydrated instead of that rough, stripped texture sulfates leave behind. Marlowe actually got a little annoyed with me. "You should have made me do this two years ago." She was right.

Temperature Matters More Than You Think

Hot water opens your hair cuticle the same way sulfates do. I wash and rinse my clients with lukewarm water at the bowl, never hot. At home, you should do the same.

Here's the trick I learned from an older stylist when I first started: finish with a cold rinse. Like, actually cold. It seals the cuticle shut, which locks in moisture and creates insane shine. My client Solenne thought I was crazy when I first suggested this. She texted me a week later: "I tried the cold rinse thing. My hair looks like glass. I'm mad I didn't believe you sooner."

Yes, cold water on your head is unpleasant. But it takes fifteen seconds and makes a visible difference. I do it on my own hair every wash day.

Custom Advice Based on What You Got Done

If You Got Color or Balayage:

The sun is your enemy. UV rays break down color molecules the same way they damage your skin. Last summer, my client Saskia went on a beach vacation two weeks after getting a beautiful warm balayage. She didn't use any UV protection. Came back and her hair had turned this weird orange-yellow and completely flat, no dimension, none of the richness we'd created. We had to do a toning treatment to fix it.

Now I tell everyone: if you're going to be outside for more than an hour, use a UV protectant spray. Between appointments, color-depositing conditioners help maintain your tone. Purple shampoo for blondes is the famous one, but there are versions for every color. I have Marlowe use one once a week, and it keeps the brass away without her needing gloss treatments as often.

If You Got a Smoothing Treatment:

Your main battle is against humidity and anything that makes your hair wet.

Our New Jersey climate throws everything at us. Humid summers, dry winters, random rainstorms. Your Brazilian Blowout or keratin treatment does most of the heavy lifting, but an anti-humidity spray adds an extra layer of protection. I keep one in my car for myself because you never know when you'll get caught in weather.

Before swimming whether in a pool or ocean, wet your hair with regular tap water first and put in leave-in conditioner. This sounds counterintuitive, but it works. If your hair is already saturated with clean water and conditioner, it can't absorb as much chlorine or salt. My client Thessaly (yes, the headband victim who's now much wiser) does this religiously before her kids' swim lessons, and her treatments last a full five months now instead of three.

Winter brings a different problem: dry indoor heat causes static. I finally broke down and bought a silk pillowcase last year after fighting static in my own hair every winter. Less friction than cotton means smoother hair while you sleep. I should have done it years ago.

The Questions I Get Asked Every Single Week

Can I still use my flat iron and curling wand?

Yes, but you need heat protectant spray every single time. Not sometimes. Every time. Heat breaks down both color and keratin treatments faster than almost anything else. I learned this when my own balayage faded in four weeks because I was lazy about heat protectant while styling for events.

Keep your tools on medium heat. The highest setting is almost never necessary and just causes damage. I keep my flat iron at 350°F, not 450°F.

When should I rebook my next appointment?

This depends on what you had done. For balayage, you'll start noticing your tone looking dull or brassy around eight to ten weeks and that's when I recommend a gloss or toning service to refresh everything. All-over color needs root touch-ups every four to six weeks. Smoothing treatments start breaking down around your hairline first, usually around month three or four. Though like I mentioned, clients who follow the aftercare rules carefully can stretch it to five months.

Is salon product actually worth the money, or are you just trying to upsell me?

I get this question from clients who've come from other salons where they felt pressured. So I'll be straight with you: professional products have higher concentrations of the ingredients that protect treated hair, and they're formulated without the sulfates and silicones that cause problems.

But I also understand budget constraints. If you're only going to invest in two products, make them sulfate-free shampoo and a heat protectant. Those two things will protect your service more than anything else.

Your Hair Is an Ongoing Investment

I think about hair services differently than I did when I started styling. It's not a one-time transaction where I do your hair and send you out the door. It's a partnership. I create the foundation in the salon, and you maintain it at home.

The clients whose hair consistently looks incredible are the ones who've figured out their at-home routine. They're not doing anything complicated. They're just consistent with the basics: washing less, using the right products, protecting from heat and sun.

If you're ever unsure about something, text me. Send me a photo. Ask questions. That's what I'm here for. I'd rather spend five minutes answering a question than have you accidentally damage the work we did together.
