- The U.S. national median for keratin smoothing is $300 per service.
- Add about 27% to any menu price for sales tax and gratuity.

- The largest single variable is notice window — cancellation windows run from 12 to 48 hours.
What the same service costs across the U.S. market
None of these figures belongs to a brand on this page. They describe the wider market, which is what you need in order to judge a quote rather than just accept it.
| Service | Market low | National median | Market high | Unit | What drives it |
|---|---|---|---|---|---|
| Keratin smoothing | $180 | $300 | $500 | per service | Smoothing treatment; results last 3-5 months. |
| Women's haircut | $28 | $69 | $140 | per cut | Normally includes consultation, shampoo and a finish style. |
| All-over single-process colour | $65 | $105 | $190 | per service | All-over root-to-tip or root retouch on virgin hair. |
| Gel manicure | $30 | $45 | $70 | per service | Cured colour; removal is often a separate charge. |
| Brazilian wax | $45 | $62 | $100 | per service | Full removal; first-timer offers are common. |
| Classic lash full set | $100 | $155 | $250 | full set | One extension per natural lash. |
National planning ranges. A quote outside these bands is not automatically wrong - check what is included before judging it.
What keratin smoothing costs in your metro tier
Rent and wages flow straight into the menu. Applying published metro cost bands to the $300 national median for keratin smoothing gives the following planning ranges.
| Market tier | Planning range | Multiplier | Example markets |
|---|---|---|---|
| Tier 1 - highest-cost metros | $405–$525 | 1.35–1.75× | Manhattan, San Francisco, Boston, Seattle, Washington DC, Miami Beach |
| Tier 2 - large metros | $330–$396 | 1.10–1.32× | Chicago, Los Angeles suburbs, Denver, Austin, Atlanta, San Diego, Portland |
| Tier 3 - mid-size metros | $282–$330 | 0.94–1.10× | Columbus, Kansas City, Charlotte, Nashville, Phoenix, Indianapolis |
| Tier 4 - small metro and rural | $210–$279 | 0.70–0.93× | Smaller cities, county seats and rural markets |
Bands scale the $300 national median by published metro cost multipliers. Planning ranges, not quotes.

The expensive errors, ranked
These recur constantly in pricing disputes. All of them are fixed by a single question asked before the service starts rather than after.

Some deposits are forfeited rather than credited.
- 2Not reading the notice window before entering a cardcosts $25–$100

Seven questions that prevent a surprise bill
Read these out. They take about ninety seconds and it is the difference between a quote and a surprise. The final question matters most — a written quote settles any dispute at checkout.
- "What is your cancellation window, and what is the charge if I miss it?"
- "Can you email or text me the quote before my appointment?"
- "What is the precise price for keratin smoothing at my hair length and density?"
- "If this runs longer than booked, does the price change?"
- "Is a shampoo, blow-dry or finish included in that price, or billed separately?"
- "If I join the membership today, is there an enrolment or annual fee on top?"
- "Do you take a deposit, and does it come off the final balance?"
Finally: get the quote on paper. A text or email costs the salon nothing and removes any argument at checkout.
The sensible total, worked through
This is the gap that surprises people. Starting from a $300 base, here is where the money goes by the time the card is out.
| Line | Amount | Note |
|---|---|---|
| Base service | $300 | The line you see on the menu |
| One typical add-on | $61 | Accepted at the chair without a stated price |
| Subtotal | $361 | Before tax and gratuity |
| Sales tax at 8.0% | $28.88 | Varies by state and city; services are taxable in some states only |
| Gratuity at 22% | $79.42 | Calculated on the service, not on tax |
| Sensible total | $469.30 | 56% above the menu price |

Twelve months of keratin smoothing, priced out
A single $300 appointment is easy to justify. Maintained every 16-18 weeks, keratin smoothing becomes a $1,080 annual commitment at the national median — and that is the number worth deciding on.
| Provider level | Per visit | Visits/yr | Service spend | Gratuity | Annual total |
|---|---|---|---|---|---|
| Budget provider | $180 | 3 | $540 | $108 | $648 |
| National median | $300 | 3 | $900 | $180 | $1,080 |
| Premium provider | $500 | 3 | $1,500 | $300 | $1,800 |
Assumes 3 visits per year. Change that number and every figure in this table shifts with it.
Before hunting a reduction, check the cadence. Going from 3 to 2 visits annually keeps around $216 in your pocket at the same quality of work.
Tipping: the numbers rather than the etiquette
Tip on the pre-tax service amount. If a discount or promotion applied, the norm is to tip on the original value of the work, not the discounted price.
| Gratuity rate | On $180 | On $300 | On $500 | When it applies |
|---|---|---|---|---|
| 15% | $27 | $45 | $75 | Standard for a satisfactory service |
| 18% | $32.40 | $54 | $90 | Common default in mid-size and large metros |
| 20% | $36 | $60 | $100 | Typical for a stylist you intend to rebook with |
| 25% | $45 | $75 | $125 | Reserved for complex colour, long appointments or a rescue job |
- Card tips may be pooled or delayed to the next pay run. Ask if you want it to reach one person directly.
- On a package or prepaid series, tip each visit on the value of that visit rather than once on the whole package.
- Do not tip on membership dues, booth rent, deposits, annual fees, gift-card loads or cancellation charges — no service was performed.
- Tip the same on a redo as on the original if the redo was not the provider's fault - and speak to management rather than the provider if it was.
How this compares with the alternatives
Before deciding, it is worth seeing where this lands against the nearest alternatives on both price and what you get for it.
Common questions, answered with numbers
How much does Prepare For Keratin Treatment cost?
No brand has published a figure we could verify, so use the U.S. market range of $180–$500 for keratin smoothing, with a national midpoint of $300 per service. Verify the exact amount with the location you intend to book.
What does this cost once tax and tip are added?
The menu price is not the final price. Budget 26% more - roughly $78 extra on a $300 service - and more if you accept anything offered at the chair.
What does keratin smoothing cost per year?
Around $1,080 a year at 3 visits (every 16-18 weeks), gratuity included. That figure is considerably more helpful than the $300 per-visit price when deciding whether to commit.
Why can two salons quote such different prices?
Mostly geography. The same service name maps to roughly $210 in a rural market and $525 in the most expensive metros, a 2.5x spread. Provider tier and appointment length move it further.
How current is this pricing?
No. Everything here is either an amount published by a source listed below, or a plainly marked U.S. market range. Menus change without warning. Last reviewed August 2026.
