This is a specific conversation about Hamster supplies — what hamsters actually need — ask about yours and get one honest answer for your exact situation.

Switching from a seed mix to a balanced pelleted diet is one of the best things you can do for your hamster's long-term health — seed mixes let them selectively eat the fatty, sugary bits and leave the nutritious ones, which leads to deficiencies over time. Before I point you toward a specific product, it helps to know a little more: what species do you have (Syrian, dwarf, Roborovski?), how old are they, and have they been on the seed mix from the start or is this a more recent thing?
She's a Syrian, about 8 months old, and she's been on a seed mix since I got her at 10 weeks. She's pretty good at selective feeding — basically just eats the sunflower seeds and leaves everything else.

Classic selective feeder — sunflower seeds are essentially hamster junk food, high fat and addictive. At 8 months she's young enough to adapt well, but she will almost certainly protest the change at first, so the transition needs to be gradual. What product are you currently using, and roughly how much does she eat in a day? That'll help me give you a sensible mixing ratio to start with.
She's on Supreme Science Selective at the moment — well, that's what I bought thinking it was good, but I read it's actually a seed mix in disguise. She eats maybe a tablespoon a day but cherry-picks most of it.

You're right to question it — Supreme Science Selective is marketed as a complete food but contains enough variety that hamsters can and do selectively eat it. For a true nutritionally balanced pellet where she physically can't cherry-pick, I'd recommend Oxbow Essentials Adult Hamster & Gerbil Food. It's a uniform pellet, nutritionally complete, low sugar, and well-regarded by hamster welfare communities. It's widely available on Amazon UK. Start by replacing about 25% of her current mix with Oxbow pellets for a week, then go to 50/50 for another week, then 75/25, then full Oxbow by week four. She may go on a brief hunger strike around the 50/50 mark — hold your nerve, keep the ratio, and don't offer extra seed mix as a reward. As long as she's eating some food each day she's fine.
What if she just refuses to eat the pellets entirely and starts losing weight?

If she's genuinely not eating at all for more than 24 hours, slow the transition down rather than abandoning it — go back to 25% Oxbow for another week before trying to move forward again. Actual weight loss in a young healthy Syrian from a diet transition is uncommon; what usually happens is they eat less for a few days while they adjust. If you're concerned, a kitchen scale is useful here — weigh her every few days. Syrian hamsters typically sit between 120–200g; if she drops more than 10% in a week, that warrants a vet check. But most owners find that once the seed mix is fully gone, hunger does the persuading.
That's really helpful. Can I still give her any treats or will that undo everything?
inparticular.ai
Treats are fine in moderation and won't undo a good base diet — the problem with seed mixes was that they were the entire diet, not occasional extras. Small amounts of fresh veg a few times a week (broccoli, cucumber, courgette) are great. Mealworms are a good protein treat, especially useful during the transition as she'll find them hard to resist. Just avoid fruit, honey-coated or yoghurt treats, and anything with added sugar — Syrian hamsters are prone to diabetes and those products are genuinely risky. One or two mealworms alongside her Oxbow pellets in the early days can help build a positive association with the new bowl.
