Hair treatments and masks are designed to give the hair and scalp more concentrated care than an everyday conditioner. Depending on the formula, they can help replenish moisture, improve softness, support strength and make dry, damaged or stressed hair feel more manageable.

At Vault, we curate treatments across a range of formats, from rich conditioning masks and overnight formulas to targeted scalp treatments and strengthening care. Some are designed for occasional use, while others can be worked into a regular weekly routine depending on what your hair needs.

Choosing the right treatment comes down to your main concern. Dry or coarse hair may benefit from a more nourishing mask, while weak or processed hair can suit strengthening formulas. If the scalp is the focus, look for treatments specifically designed to support scalp comfort and condition.

Frequently Asked Questions

How often should I use a hair mask?

It depends on the formula and your hair type. Many masks are used once or twice a week, while some intensive treatments may be recommended less frequently.

Are hair masks good for damaged hair?

+

They can be. Hydrating and strengthening masks may help improve the feel and manageability of dry, brittle or processed hair, although results depend on the formula and level of damage.

Can I use a hair treatment overnight?

+

If the product is specifically designed for overnight use. Follow the individual directions, as not all masks or treatments are intended to be left on for extended periods.

Should hair masks go on the scalp?
