How Long Does a Biowave Last - and How to Care for It

A biowave changes your hair's natural texture and gives you curls that hold their shape without a curling iron every morning. Below: how long the effect lasts, what influences it, and how to care for your curls - straight from the stylists at Chicago salon in Kazan.

On average, a biowave lasts anywhere from 2 to 6 months. For some, hair stays curly enough for months; for others, the curl starts to noticeably loosen much sooner. The difference isn't just about the formula - your starting hair, its length, its density, the curl diameter, and how you care for it at home all play a role.

At Chicago, we pick the biowave around the result you want and the way your hair behaves. This piece covers how to get more mileage out of your curls, how to wash and dry your hair after the treatment, and when it's time to book a touch-up.

How long does a biowave last?

The ballpark figure is 2 to 6 months. It's not a warranty period - the exact lifespan depends on your individual hair and how the procedure is performed.

Worth keeping in mind: the curl doesn't vanish overnight. Over time it gets softer, strands stretch out, and the hairstyle shifts toward a wavier, looser look. So judge the result not just by whether the original curls are still there - but by whether you're comfortable wearing the new texture.

Here's what shapes how long the effect lasts.

1. Hair structure and condition

Hair varies in thickness, density, elasticity and porosity. These traits decide how a strand reacts to the perming formula and how well it keeps the shape it's been given.

Soft, fine hair often takes to a texture change more easily. That said, condition matters: already-damaged strands can react unevenly and lose that clean, polished look faster.

Dense, coarse hair sometimes needs a more careful technique. If strands are long and heavy, their own weight can gradually pull the curl out. That's why you can't guess how long a wave will last from hair type alone - the stylist checks several things at once before the procedure.

2. Length and curl size

The longer the hair, the more its weight affects the curl shape. On short cuts, curls often stay defined longer, while on long strands they gradually drift into soft waves.

Curl diameter matters too. Big curls look natural and free - but they can also lose their initial crispness faster. Tighter curls are usually more noticeable as the texture relaxes. That doesn't mean going for the tightest possible curl for longevity's sake - what actually matters is matching the curl size to your length, your haircut shape, and the look you want.

3. Coloring and past treatments

Coloring, especially lightening, can change your hair's porosity and strength. If strands are already damaged, more chemical processing can worsen dryness and breakage.

Still, colored hair isn't automatically off-limits for a biowave. The decision comes down to the current state of your hair, your treatment history, and whether the chosen formula plays nicely with what's already been used.

Always tell your stylist if you've recently lightened, done a complex color job, had keratin smoothing, or any other structural treatment. Sometimes it makes more sense to first get the hair back into decent condition - or to skip the wave entirely if the risk of damage is too high.

4. Home care and heat styling

After a biowave, hair may become drier and more sensitive to mechanical stress. Frequent use of a hot dryer without heat protection, plus flat irons and curling wands, can make strands look worse and curls less defined.

A well-chosen care routine helps maintain elasticity, reduces frizz and makes the curl easier to shape. But no cosmetic product can lock in the original form forever - over time, the texture will change.

How to care for your hair after a biowave

The main goal of aftercare is to keep the hair hydrated enough, reduce mechanical damage, and help the curls hold their shape.

The first 48–72 hours

Treat your hair extra gently in the first days after the wave. The exact restrictions depend on the formula and procedure protocol, so first and foremost follow your stylist's advice.

Usually you're advised to:

• not wash your hair for as long as your stylist recommends;
• not pull it into a tight ponytail or a firm bun;
• avoid tight braids, clips and accessories that leave kinks;
• not flat-iron your strands or try to straighten the curl on purpose;
• not go to bed with wet hair.

Don't test how well the wave holds right after the salon with a full styling session. Give your hair its initial adjustment period, and judge the result under normal everyday conditions.

How to wash your hair after a biowave

Go for a gentle shampoo that suits your scalp and doesn't leave hair overly dry. Sulfate-free formulas can be a nice option for some hair types, but the absence of sulfates doesn't guarantee perfect care on its own - the overall formula and how your hair reacts matter more.

When washing, stick to a few rules:

1. Use warm - not hot - water.
2. Apply shampoo mostly to the scalp, without scrubbing the length too hard.
3. Don't wring your hair into a twist or tangle it while rinsing.
4. Rinse the product out thoroughly so residue doesn't weigh strands down.
5. After washing, gently blot your hair with a towel - don't rub it.

How often you wash should come down to how your scalp feels. You don't need to walk around with dirty hair just to "protect" the curl - it doesn't extend the biowave's life and can be uncomfortable.

What products do curls actually need

After the procedure, it's worth rethinking your usual lineup. Your hair may need extra products for softening, detangling, and defining curls.

Conditioner helps untangle strands, reduces friction and makes hair more cooperative. Apply it to the length, focusing on the spots that tangle most.

A moisturizing mask keeps hair soft and elastic. How often you use it depends on your hair's condition and the manufacturer's guidance. Formulas that are too heavy can flatten volume and drag down tighter curls.

A leave-in product - cream, lotion or a light conditioner - helps cut down frizz and makes styling easier. Pick the formula based on your hair's thickness and porosity.

Styling for curls - foam, mousse or gel - lets you emphasize the curl shape. Start with a small amount and build up only as needed.

You don't need to buy the whole curly-hair aisle. It's far more useful to pick a couple of products that solve specific problems and don't weigh your length down.

How to dry your hair so curls don't frizz

Drying method makes a big visual difference. Even a well-executed biowave can look sloppy if you aggressively rub your hair with a towel or brush it out while dry.

For more defined curls, try this sequence:

1. After washing, gently blot out excess water with a soft towel.
2. Distribute a suitable leave-in product through the damp length.
3. Carefully squeeze strands upward with your palms to help them clump into curls.
4. Let your hair air-dry, or use a dryer with a diffuser on medium heat and low airflow.
5. Don't poke at the curls too much while drying - that's what ramps up frizz.

If you prefer air-drying, don't leave your hair wet for an excessive amount of time. If you use a dryer, avoid overheating and, where possible, apply a heat protectant that suits your styling routine.

Can you brush your hair after a biowave?

Yes, but the way you brush matters. Wet hair is more vulnerable to stretching and mechanical damage. After applying conditioner, gently detangle the length with your fingers or a wide-tooth comb, starting at the ends and working your way up.

Dry curls shouldn't be aggressively run through a regular brush if you want to keep their defined shape - it can break the curls apart and boost frizz.

If the shape loses definition by morning, try lightly misting your strands with water, adding a little of the right styling product, and reshaping the curls with your palms. In most cases that's enough to refresh your hair without a full wash.

How to extend the life of your biowave

You can't fully stop the natural loosening of the curl - but good care keeps the hair looking good for longer.

Don't overload your length with products. Too much oil, heavy masks, and styling product will weigh the strands down. It's especially noticeable on fine hair and with large curls.

Cut back on flat irons and curling wands. Regular high heat can degrade the hair's quality. If you want to switch things up now and then, go for gentler styling methods and use heat protection.

Keep the cut in shape. As hair grows out, the volume distribution and curl placement shift. A timely trim keeps the proportions of your hairstyle right and makes the curl look neater.

Keep an eye on your ends. If the length starts feeling dry and tangling, adjust your routine. Sometimes it's better to trim damaged ends than to try to make up for them with lots of product.

Don't repeat the wave too often. Even fairly gentle formulas affect hair structure. Before the next round, the stylist should assess the length and confirm it's ready for another chemical pass.

How to tell the biowave is starting to straighten out

Gradual shape change is a normal part of a biowave's life cycle. Over time you might notice the curls getting bigger, the pattern less defined, and the root volume sitting differently.

The key thing is to tell natural loosening apart from your hair actually getting worse. If your hair still feels soft, comb normally, and doesn't snap - the loosening shape change on its own doesn't mean the procedure was botched.

The other scenario is visible dryness, more tangling, loss of elasticity, or breakage. In that case, book with your stylist, rethink your home routine, and pause any further chemical treatments for now.

Don't try to force the original shape back with a repeat wave or intense heat styling. First, figure out what's actually happening with your hair and what care it needs.

When it's time for a repeat biowave

Going strictly by the number of months that have passed isn't the smartest approach. For some clients, the comfortable gap between treatments turns out shorter; for others, noticeably longer.

Before a repeat biowave, you need to check:

• how defined the remaining curl is;
• how your hair's condition and elasticity have changed;
• whether there are dry or damaged patches;
• how the grown-out length is affecting the hairstyle's shape;
• whether you've had coloring, lightening or other chemical treatments recently.

A full-length reapplication isn't always necessary. Depending on the technique and the state of your hair, the stylist may suggest an alternative or recommend postponing. The real benchmark isn't how quickly you can get the original curls back - it's whether you can get a predictable result without overloading your hair.

Who's a good fit for a biowave, and how to prepare

Biowave can suit anyone who wants a long-lasting texture, more defined curls, extra visual volume, or less time spent on daily styling.

But not everyone is a good candidate. Be especially cautious with heavily lightened, brittle, very dry, or previously over-processed hair. Sometimes the smartest move is to skip the treatment altogether.

Before booking, try to remember what products and treatments you've used over the last few months. If your hair is colored, tell your stylist about the technique used and the degree of lightening - that helps assess compatibility and choose the right approach.

At Chicago, biowave is done using formulas from several professional brands. The specific option is chosen based on hair length, the result you want, and the starting condition of your hair. You can see our services on the Chicago site.

If you're not sure which curl will work for you, start with a consultation. Talking through the result you want and getting your hair assessed helps avoid unrealistic expectations and lands you on a shape that works in everyday life.

Frequently asked questions about biowave

How many months does a biowave last?

On average, 2 to 6 months. It depends on hair structure and length, curl size, the formula used, and home care. Gradual loosening of the curls is a normal part of the procedure.

When can I wash my hair after a biowave?

Usually you're advised to wait 48–72 hours, but the exact time depends on the formula and the procedure protocol. Follow the guidance of the stylist who did your wave.

Can I get a biowave on colored hair?

In many cases yes, if your hair is in good enough condition. After heavy lightening or other chemical treatments, you may need extra assessment, a strand test, or to skip the wave.

Do I need a sulfate-free shampoo?

Not necessarily. A gentle shampoo that doesn't dry out your hair and suits your scalp is the more important criterion. Sulfate-free options can be handy if they work well specifically on your hair.

Why does hair get frizzy after a biowave?

Frizz can come from higher porosity, insufficient conditioning, friction during drying, or the wrong styling product. Handle the length more gently, use conditioner, and shape curls while hair is damp. If you also notice visible breakage, check in with your stylist.

Can I straighten my hair after a biowave?

Temporarily smoothing curls with styling is usually possible, but regular high-heat treatment raises the risk of damage. Use a heat protectant, keep the temperature moderate, and don't try to pull your hair straight every day if you want to keep it in good shape.

How often can I repeat a biowave?

There's no universal interval. It depends on your hair's condition and the technique. Before a repeat, assess the length and rule out excessive chemical stress on already-treated sections.

Can I sleep with wet hair after a biowave?

Better not. Wet hair is more vulnerable to mechanical stress, and friction against the pillow can increase tangling and frizz. Where possible, time your washes so the curls have time to fully dry before bed.
