Quick answer

Black Friday 2026 is Friday 27 November, Cyber Monday is 30 November, and UK retailers typically run the pricing from early November through to the Monday. Buy in the week before or on the day if the listing passes three checks: the was-price has not climbed since September, the model is current, and the seller is the retailer. Otherwise hold.

Seven things on the listing that settle it

Ask when to buy hair straighteners on Black Friday UK and you get a date back. The date is public and settles nothing: whether the pair you have open is really cheaper is written on the listing, not the calendar. Seven things on that page answer it, each in under ninety seconds.

The was-price, and whether it climbed to get there

Start with the struck-through number. It only means something if the retailer actually sold at it for a reasonable stretch, and a price tracker shows you: Keepa and CamelCamelCamel for Amazon listings, PriceSpy or PriceRunner for the wider UK shops. Widen the graph to a year. If the line sits flat, steps up in October and drops back in November, the discount is measured against a number nobody paid for long. Your own note of the September price is the simplest version of the same check.

Current generation, or last year's

The deepest reductions tend to sit on the model being replaced. Compare the full model name on the listing with the brand's own site: if the brand shows a newer version at full price, the retailer's deal is a clearance and should be priced like one. Sometimes the old one is the right buy; decide that on purpose.

Retailer exclusives and gift-set bundles

Premium brands protect the price of their core tool by moving the discount somewhere else: a colour sold by one retailer only, or a box with a heat mat and a travel bag. An exclusive colour has no price history to compare against, which is exactly why it exists, and a gift set hides the price of the tool inside the extras. Subtract what the extras would cost alone, or price the standard colour of the same model.

The brand's own site

Open the manufacturer's page in a second tab. If ghd, Dyson or Cloud Nine shows the same reduction, the brand is setting the price. If the brand is at full price and one retailer is far below it, either the retailer is funding the cut, which the big chains do, or the listing is not what it seems; the next two checks tell you which.

Stock, the seller and the plug

Scroll to the seller line. On Amazon and on the marketplace sections of larger retailers, "sold by" and "dispatched by" can name a third party, and a suspiciously low price on a premium styler is very often a grey import: a unit meant for another market, sometimes with a two-pin plug and an adaptor in the box, and usually outside the UK guarantee. Buy from the retailer itself or the brand.

"Only 3 left" is partly a sales tactic, but on a popular model in late November it is often true, and a pair that sells out on the Friday morning is rarely restocked at the same price. Low stock on a listing that passes the other checks is a reason to buy.

The guarantee

Most brands only honour their guarantee on units bought from an authorised UK stockist, and the list is on the brand's site. Check it before the sale, and register the product when it arrives.

How the main brands tend to behave

The waiting pays differently by tier. None of this is a measured figure, only the widely observed shape of the market, and it can change in any year.

At the top, ghd keeps tight control of its pricing all year, and the same is broadly true of Dyson's Corrale and Cloud Nine. Reductions on the core model tend to be shallow and short-lived, with the movement coming through gift sets, limited-edition colours and retailer exclusives. In the middle, BaByliss, Remington and Shark tend to move more on the tool itself, and this is where the fortnight before Black Friday earns its keep. Salon names such as Hershesons sit between. Budget own-brand straighteners barely move, so buy those when you need them.

One case the calendar does not help is afro and tightly coiled hair, where a flat iron is often the wrong tool at any price. A heated comb gets closer to the root with less tension; our hot comb straightener for afro hair review covers what to look for before you shortlist a pair of plates that will fight your hair.

September to January, month by month

The dates below are typical patterns, not announcements. Retailers shift their windows by a week or so between years; what stays constant is the order of events.

September: nothing on sale yet, so take the record

There is nothing to buy in September and that is the point. Pick two or three models, open the exact listings you would buy from, and write down today's price and the RRP for each. Set tracker alerts. The September price is the one reference the retailer cannot rewrite.

October: previews, Prime-style events and the first creep

October brings "Black Friday preview" landing pages and Amazon's autumn Prime-style event, which pulls some hair-tool pricing forward. Early reductions on mid-range models are sometimes real and worth taking if they beat your walk-away price. It is also when was-prices start to climb on listings being lined up for a November "reduction", so glance at the tracker graphs weekly.

Early November: the previews turn into a sale

From the first week or two of November most UK retailers roll into Black Friday pricing and the sale becomes a month-long event. Check your shortlist against the September record, not the was-price: if a listing is already under your walk-away price and passes the checks, waiting three more weeks buys little and risks the stock.

The week before: 20 to 26 November

Typically the busiest week for movement, when new reductions land on models that sat still through early November. Check the shortlist daily, watch stock, and compare the retailer against the brand's site. If a premium model appears this week as an exclusive or a gift set, that is probably the shape its deal will take.

Friday 27 November: the day itself

Check the shortlist first thing. On most lines the Friday price is Thursday's; on a few it drops further, and on popular models the stock can be gone by mid-morning. Run the seven checks on anything that has moved, and buy if it passes. Baskets do not hold stock.

Monday 30 November: Cyber Monday

Usually the tail of the same event, with the Friday price carried through the weekend. Its value is a second chance on anything that sold out, and occasionally a further cut on a model the retailer has too many of.

December: the drift back, then Boxing Day

Between Cyber Monday and Christmas, prices on current models tend to drift back up while gift sets hold, so the set is usually the better December buy. Boxing Day tends to clear the sets and colours that did not sell, and mid-range tools sometimes return to their November price.

January: where last year's model bottoms out

January is quiet for the current model and busy for the previous one, which retailers tend to run down ahead of spring launches. If November did not offer last year's version at a good enough reduction, this is where it is most likely to bottom out. Grey-import listings also thicken in January, so the seller check matters more, not less.

The buying procedure, in order

The whole job, in order. Most of it happens before the sale starts.

  1. Shortlist two or three models now. One you would be pleased with, one you would settle for, and in the premium tier, one previous-generation option. Note each full model number.
  2. Record the current price and the RRP. The price on the exact listing you would buy from, and the RRP on the brand's site.
  3. Set price-tracker alerts. Track the exact listing, not the model name: two listings of the same pair carry different histories.
  4. Check the plates against your hair. Plates around an inch wide suit most lengths; narrower suits short hair and fringes, wider suits long thick hair. Ceramic is gentler, titanium runs hotter. Fine or coloured hair wants adjustable temperature so you can stay well under the maximum; our guide to protecting hair from heat damage explains which settings suit which hair.
  5. Decide your walk-away price before the sale. The number at which you will buy without waiting for further drops. Deciding it in October, with no countdown timer on the page, is what stops the panic buy.
  6. Check the shortlist on Black Friday morning. Run the seven listing checks on anything that has moved. Ignore the percentage on the badge and compare the sale price with your September record.
  7. Verify the seller, the plug and the guarantee at the checkout. Sold and dispatched by the retailer or the brand, UK three-pin plug, seller on the authorised stockist list.
  8. Buy or hold. If the listing passes and the price is at or under your number, buy. If it fails a check, hold, and look again on Cyber Monday and in January.

What goes wrong, and how to recover

The discount is against an inflated was-price. You bought at a "reduction" that lands where the listing sat in September. Online orders carry a 14-day cancellation right under the Consumer Contracts Regulations 2013, from the day after delivery: tell the seller you are cancelling, then return the goods.

You bought last year's model without realising. Compare the model number on the box with the brand's current range. If the reduction was shallow, cancel within the 14 days and rebuy the current one or wait for January.

The pair arrives with a two-pin plug. A grey import. Return it as not as described, through the marketplace's guarantee scheme if the seller is unhelpful, and rebuy from the retailer or brand; the brand's guarantee will almost certainly not cover it.

The gift set hid the price of the tool. Take the set price, subtract what the extras cost separately, and if the tool came out dearer than its standalone listing, the 14-day right applies to the whole set.

Stock ran out and you panic-bought something else. If the substitute is a model you never shortlisted, cancel inside the window and wait for the January clearance.

You waited for Cyber Monday and the deal went. Nothing brings it back. Watch the listing through December, where prices occasionally dip back for a day, and fall back on last year's model in January.

The returns window closes over Christmas. The statutory 14 days runs from delivery, not Christmas Day, so a pair bought on Black Friday and opened on 25 December is outside it. Many UK retailers extend gift returns into January, but that is policy rather than right, so check before buying a present.

Frequently asked questions

My straighteners have died. Should I wait until Black Friday?

No, if you use them most days, buy a replacement now in the tier you actually need. Going without for two months to chase a reduction that may not come is a poor trade, and nothing stops you buying the pair you really want in November and keeping this one for travel. If they still work but are failing, hold until the week before the sale.

Do ghd straighteners go on sale on Black Friday?

The core ghd styler tends to hold its price year-round, and the reductions that do appear tend to come through gift sets, limited-edition colours and retailer exclusives rather than a deep cut on the standard model. That is the observed pattern, not a promise for 2026. If ghd's own site shows no reduction, a retailer showing a large one deserves the was-price check first.

Is Cyber Monday better than Black Friday for hair straighteners?

Usually neither: in the UK the two are typically one event with a Monday tail, and most retailers carry the Friday price through the weekend. Cyber Monday is a second chance on anything that sold out. If your pair is at a new low on the Friday and stock is thin, take it then.

How do I tell if a Black Friday discount is real?

Paste the listing into a price tracker and look at the last twelve months, not the last week. A real reduction sits below where the listing has been for most of the year. A fake one is a was-price that climbed in October and a sale price that lands roughly where the listing already was in September.
