What order should I use shampoo, mask and conditioner on hair extensions?
Shampoo first, treatment mask second, conditioner last. That order surprises people, because most of us learned to condition and then mask, or to skip the conditioner on mask days. For hair extensions the reverse sequence works better, and the reason comes down to how the cuticle behaves when it is wet.
Why the mask goes before the conditioner
Freshly shampooed hair has an open cuticle. That is the moment a rich treatment can actually get into the hair rather than sitting on top of it. If you condition first, the conditioner does its job of smoothing and closing the cuticle, and the mask you apply afterwards has far less to work with.
Applying the mask second and the conditioner last means the treatment absorbs while the hair is receptive, and the conditioner then seals everything in. Think of the conditioner as the final step that locks the door behind the mask.
For extension hair this matters more than for your own hair. Extension hair cannot replenish itself from a follicle, so the moisture it gets from a mask is the only moisture it has until the next wash. Sealing it properly is what keeps the lengths soft for the days in between.
Step one: shampoo the scalp

Wet the hair thoroughly with warm, not hot, water. Apply shampoo to the scalp and roots, where oil and product actually build up, and massage with fingertips rather than nails. Let the lather run down the lengths as you rinse instead of scrubbing the extension hair itself.
Two things to avoid: piling the hair on top of your head, which tangles wefts and tapes, and rubbing the lengths together. Work in the direction the hair falls.
If your hair is very oily or you have used a lot of styling product, a second, lighter shampoo at the scalp is fine. Rinse until the water runs clear.
Step two: treatment mask on the mid-lengths and ends

Squeeze excess water out gently so the hair is damp, not dripping. Take a small amount of mask and smooth it through the mid-lengths and ends, starting a few centimetres below the attachment points and working down.
Keep it off the bonds, tapes or wefts. Conditioning ingredients can soften adhesive and shorten the life of the install, and they are not needed there anyway since the attachment point does not dry out the way the ends do.
Leave the mask for five to ten minutes. This is a good moment for the rest of your shower. Rinse thoroughly. Once or twice a week is plenty for most people; if your hair is very dry, coloured or you live somewhere hot, lean towards twice.
Step three: conditioner last

On the days you mask, follow with conditioner. On the days you don't, the conditioner still comes after the shampoo. Apply a small amount through mid-lengths and ends, again below the attachment points, leave for one to two minutes, and rinse with cooler water. Cooler water helps the cuticle lie flat, which is where shine comes from.
If you find the conditioner too much on mask days, use less rather than skipping it. The seal is the point.
After the shower
Blot with a towel rather than rubbing. A microfibre towel or a soft cotton T-shirt is kinder than terry cloth. Detangle from the ends upward with a wide-tooth comb or an extension-safe brush, holding the hair above the section you are working on so the attachment points take no strain. Dry the roots and attachment areas fully before bed; damp bonds and tapes are the most common cause of slipping.
How often to run the full ritual
| Step | How often |
|---|---|
| Shampoo | Every wash, two to three times a week |
| Treatment mask | Once or twice a week |
| Conditioner | Every wash |
The Hadrill ritual in this order
The Hadrill collection is designed around exactly this sequence. The Shampoo cleanses the scalp with caffeine and rosemary. The Treatment Mask hydrates the lengths with eight plant-based oils, shea, aloe, biotin and propolis. The Conditioner seals with five oils and an amino acid lipid complex. All three are protein-free, sulphate-free, paraben-free, silicone-free and extension-safe, so the order above can be followed without a second thought about the bonds.
Frequently asked questions
Can I skip conditioner if I have used a mask?
It is better not to. The mask delivers moisture; the conditioner seals the cuticle over it. Without the seal, much of what the mask gave you rinses away or lifts out over the next day.
Should I use the mask on my scalp?
No. Masks are for the mid-lengths and ends. The scalp needs cleansing, not heavy conditioning, and mask at the roots can leave both your hair and any attachment points feeling greasy or loose.
Can I leave the mask in longer than ten minutes?
There is little benefit beyond ten minutes, and on extension hair long soaks can soften adhesives if any product migrates upward. Five to ten minutes is the sweet spot.
How far from the bonds should I keep the mask and conditioner?
Start two to three centimetres below the attachment point. The hair nearest the bond is the newest and least dry, so it needs the least product.
Does this order apply to clip-ins I wash separately?
Yes. Wash clip-ins in the same order in a basin, lay them flat to dry, and keep the mask away from the clips and the weft base.
