L’Oréal Professionnel Metal Detox Discovery Gift Set: Shampoo, Hair Mask & Hair Oil (100ml, 75ml & 30ml)

If your hair feels dull or a bit worse for wear after hard-water exposure, this Metal Detox Discovery Gift Set is a sensible place to start. It’s a mini trio designed for coloured and damaged hair, with a clarifying shampoo, a colour-protecting mask and a concentrated hair oil to finish.

That said, it’s worth keeping expectations realistic: a discovery set is small by design, so it’s more about trying the routine and seeing how your hair responds than about replacing a full-size stash straight away.

Key points

This set is built around a simple routine: cleanse with the Metal Detox shampoo, follow with the colour-protecting mask, then seal the look with the concentrated hair oil. The formula is enriched with Glicoamine, positioned to cleanse the hair and help remove impurities. Over time, the goal is to support smoother feel and shine, while helping protect against breakage and colour fade from external damage.

Where it tends to make the most sense is if you’re noticing your hair doesn’t feel as fresh as it should—especially if your water is hard and you want to prevent dullness and loss of vibrancy. For everyday use, the steps are straightforward, and the sizes make it easy to keep in your bathroom or travel without committing to full bottles immediately.

The essentials

The routine here is clearly meant to work together. Use the shampoo on wet hair, then combine it with the mask for what the set calls “optimal results”. Finish with the serum/oil for added protection—this is often the bit people skip when they’re rushed, but it’s also one of the most noticeable for shine and smoothness.

A practical way to judge whether it suits you: try it on a normal wash day, then assess how your hair feels over the next 24–48 hours. If you’re already colouring your hair or you’re dealing with roughness and breakage, this set’s focus should align with what you’re trying to fix.

Key takeaways

What stands out on paper is the combination of cleansing + targeted treatment + finishing oil. That “three-part” approach usually helps when your hair needs more than just shampoo, but you still want something manageable for routine days.

The oil being concentrated can be a win if your hair gets frizzy, tangles more easily, or simply looks less glossy than you’d like. But there’s a limit: if your hair is very fine or you tend to go heavy on oils, you may need to use a small amount to avoid weighing the hair down.

Also, if your main concern is something unrelated to colour fade, impurities or hard-water build-up, this set may end up being a bit misaligned. It’s specific in purpose, not a general-purpose repair kit.

Who it’s for

Worth considering if you have coloured hair and you’re trying to help prevent colour fade, particularly where hard water is a factor. It can also suit anyone who’s dealing with visible damage and wants a routine that focuses on smoothness, shine and protection against breakage.

It may not suit you as well if you’re looking for a simple one-step shampoo-and-go solution, or if you dislike any product feel that comes with masks and oils. In that case, you might prefer a more minimal routine.

Is it worth it?

Buy this Metal Detox Discovery Gift Set if you want an easy, structured routine to help protect colour and reduce the look of impurities—especially if hard water has been an issue for you. The discovery sizes are also a decent move if you’re not sure how your hair will react yet, but still want to try the full shampoo → mask → oil sequence.

Skip it if you need a budget full-size replacement or you prefer a low-effort routine, because masks and concentrated oils can be overkill for some hair types. It also might not be the best match if your hair concerns aren’t connected to colour fade, impurities or external damage.

Quick questions before you buy

• Is this mainly for coloured hair? It’s described as colour-protecting, with benefits aimed at coloured and damaged hair.
• Can you use the shampoo on its own? The set suggests combining the mask for optimal results, and finishing with the oil for added protection, but you could still use the shampoo separately if you prefer.

• What should you expect to improve? The set targets cleansing/removing impurities, helping reduce breakage and colour fade, and leaving hair feeling smooth with added shine.
