L'Oréal Professionnel Metal Detox is a haircare range for colour-treated hair. The brand explains that metal particles in water, such as copper, can build up inside hair wash after wash, and that this can affect colour results and increase the risk of breakage during colour services.
This guide covers the shampoo and mask: what each does, the order to use them in, how often to use them at home and how to choose a size. The routine below uses Australian supplier guidance for the 1.5L shampoo and 500ml mask. Always follow the directions on your own pack.
What the shampoo and mask each do
| At a glance | Metal Detox Shampoo | Metal Detox Mask |
|---|---|---|
| What it does | An anti-metal cleansing cream shampoo. It cleanses hair and helps remove metal particles that have built up in it. | A rinse-off mask used after shampooing. |
| Apply to | Wet hair | Shampooed, towel-dried hair |
| Time | Lather, then rinse | Leave on for 1 minute, then rinse |
What order do you use them in?
- Shampoo. Apply Metal Detox Shampoo evenly to wet hair, lather into a rich foam, then rinse.
- Mask. Towel-dry your hair, apply Metal Detox Mask evenly, leave it on for 1 minute, then rinse.
These products are sold separately. If you use both, L'Oréal Professionnel recommends applying the mask after the shampoo.
The range also includes a pre-shampoo treatment that goes on before the shampoo, a conditioner, and leave-in products used after washing. Each has its own directions, which you'll find on its product page in the Metal Detox range.
How often should you use them at home?
Shampoo. For the 1.5L and 300ml shampoos, L'Oréal Professionnel's Australian supplier pages advise home use once a week, alternating with your regular Serie Expert shampoo. Follow the directions on your own pack.
The Australian supplier page for the 100ml shampoo does not state a weekly schedule. Check its own directions rather than assuming the same frequency applies to every size.
Mask. The supplier directions for the 500ml and 250ml masks don't state how often to use them, so follow the directions on your pack.
Home use and salon treatments
The Australian supplier directions for the 1.5L and 300ml shampoos include separate instructions for hairdressers and for home use. The professional directions tell hairdressers to follow the shampoo with the Metal Detox mask. For home use, they advise once a week, alternating with your regular Serie Expert shampoo.
L'Oréal Professionnel also describes an in-salon Metal Detox protocol, carried out by a hairdresser, and the mask is part of both the salon and home routines. If you'd like to know more about the salon protocol, ask your hairdresser at your next visit.
Which size should you choose?
| Product | Size | Worth knowing |
|---|---|---|
| Shampoo | 100ml | Travel size |
| Shampoo | 300ml | Smaller bottle |
| Shampoo | 500ml or 500ml refill | The refill is a pouch for topping up a bottle you already have |
| Shampoo | 1500ml (1.5L) | Largest bottle |
| Mask | 75ml | Travel size |
| Mask | 250ml | Mid size |
| Mask | 500ml | Largest size, a salon size |
A few things to weigh up:
- How often you'll use it. Consider your wash routine and the directions for your chosen product before choosing a larger size.
- Who will use it. If more than one person at home will use it, a larger size means buying less often.
- Trying it or travelling. The 100ml shampoo and 75ml mask are the travel sizes.
- Space. The 1.5L bottle and 500ml mask are the largest packs, so check you have room in your shower or bathroom.
