Rank #5 in Best Hair Straighteners 2026: 10 Ranked, and the Numbers That Don't Add Up
Remington Keratin Protect S8598 Hair Straightener
Price and rating as shown on Amazon when we collected them. Both change.
The Remington Keratin Protect Intelligent Hair Straightener (S8598) is the fifth entry in this guide. It costs £65.98, holds 4.6 out of 5 from 6,250 ratings, and leads on heat: five digital settings from 160°C to 230°C with a 15-second heat-up. That 230°C ceiling is higher than the £186 ghd Platinum+ at 185°C in this guide, which is a reminder that the temperature on the box is a poor guide to what you pay — here you reach further up the scale for about £120 less.
The number worth reading twice is the protection claim. The bullet promises "three times more protection from damage", and the asterisk underneath explains the comparison: straightening with the intelligent heat protection sensor turned off. That is this same S8598 with its own feature disabled, not a rival straightener. The listing is also inconsistent about the plates: the spec table lists the material type as titanium, while the bullets and the model name describe enhanced ceramic coated plates infused with keratin and almond oil. Everything on this page is taken from the Amazon listing — we have not tested the straightener ourselves.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Great length on the cord, giving plenty of room to move around. The display is great, and the audio beeps let you know exactly when it's ready to use.My eight-year-old can use these perfectly without burning her hair - the visual temperature display is brilliant so she knows exactly what heat she's using and won't overdo it. The keratin and almond oil infused plates leave hair feeling smooth and glossy after each use, and it heats up quickly so there's no long wait around.Overall, it's really good quality and feels sturdy in the hand. It also comes with a nice case to pop it away in, which is handy for storage or travel.”
Verified purchase“Smooth glide over hair and good straightening. I like the choice of temperature settings - especially good for people with dry hair. Slightly wider plates but that's fine for me as I only use to straighten not curl. Good value for money in my opinion.”

What do the 6,250 ratings break down into?
