The best deep conditioner for damaged hair is a rinse-out mask with humectants and softening oils, applied to damp mid-lengths and ends once or twice a week. Chérie's Deep Conditioning Hair Mask ($26.99) fits that description: macadamia oil, bamboo extract and hyaluronic acid, left on for 5-10 minutes, then rinsed. It improves softness and manageability. It can't rebuild broken hair, and no honest product can.
The fix: Chérie Deep Conditioning Hair Mask — formulated for exactly this.
What "damaged" actually means
Damaged hair is hair whose outer cuticle has lifted, chipped or worn away. Heat, bleach, tight styles, rough towel-drying and harsh cleansers all do it. Once a strand is broken, no jar glues it back together.
What a good deep conditioner does is smooth and soften the surface and pull in moisture, so strands snag less, tangle less and break less during styling. That's worth having. Expect better feel and less frizz, not a miracle. A trim is the only real fix for split ends.
What to look for in a deep conditioner
A humectant
Dry, damaged hair loses water fast. Hyaluronic acid is a humectant, meaning it attracts water to the strand. It's the reason a good mask leaves hair feeling plump rather than just coated.
An oil that softens
Macadamia oil is rich and emollient. It softens rough, lifted cuticles and makes hair easier to detangle. On coarse, curly or textured hair, that slip matters a lot.
A format you'll use
Here's my slightly unpopular opinion: the "strongest" mask is worth less than the one you'll use every week. A mask used twice a week beats a fancy one used twice a year. Choose a texture and a time commitment you can live with. Five to ten minutes is realistic. An hour isn't.
Our pick: Chérie Deep Conditioning Hair Mask
The Deep Conditioning Hair Mask ($26.99) is built around exactly those three things: macadamia oil, bamboo extract and hyaluronic acid. It's made for dry, damaged, curly and textured hair of every type.
How to use it:
- Shampoo first, then apply the mask to damp hair.
- Work it through mid-lengths to ends only. Keep it off the scalp.
- Leave it on 5-10 minutes, then rinse it out.
- Use it 1-2 times a week.
Mid-lengths and ends are the oldest part of your hair, so they take the most damage. That's where the mask goes.
A mask can't do it alone

People blame their conditioner when the real problem is what happens the other six days. A deep conditioner is one step in a routine, and the routine is what protects the result.
Step 1: Cleanse without stripping
The Hydrating Sulfate-Free Shampoo ($23.99) is a rinse-out cleanser with niacinamide, hyaluronic acid, aloe and jojoba. Massage it into wet hair, lather, rinse. Cleansing with sulfates and then masking is like mopping a floor while it's still being scuffed.
Step 2: The mask
See above. Rinse-out, mid-lengths to ends, once or twice a week.
Step 3: Leave-in protection
The All-In-One Leave-In Conditioner ($23.99) stays in your hair. Smooth it into damp hair before styling. It combines heat protectant, detangler and frizz control, with camellia, flaxseed and macadamia oils. This is the step that keeps daily styling from undoing your mask.
Step 4: The scalp
The Revitalize Scalp Serum ($38.99) contains caffeine, rosemary and Italian propolis. It's a leave-in for the scalp, not the lengths. After showering, massage a few drops directly into the scalp, AM and/or PM, daily. Don't wash it off. It's scalp care, not a hair-repair treatment, and it won't mend damaged ends. A comfortable scalp is simply a better foundation for the hair that grows from it.
Common mistakes with deep conditioners
- Putting it on the scalp. The mask is for mid-lengths to ends. Keep it off the roots.
- Using it daily. More isn't better. Stick to 1-2 times a week.
- Skipping the trim. Split ends travel up the strand. Conditioner won't reverse them.
- Applying to bone-dry hair. Damp hair is the instruction for a reason.
The bottom line
If your hair is dry, brittle or heat-worn, start with the mask, then fix what surrounds it: a sulfate-free cleanser, a leave-in with heat protection, and a trim when it's due. That combination does more than any single jar. Want the whole routine? The four products together are Chérie's 4-step routine, at cheriestrands.com.

Frequently Asked Questions
How often should I use a deep conditioner on damaged hair?
Once or twice a week is the right range for Chérie's Deep Conditioning Hair Mask. Apply it after shampooing to damp hair, leave it 5-10 minutes, then rinse.
Should I put deep conditioner on my scalp?
No. Apply the mask from mid-lengths to ends and keep it off the scalp. For the scalp, use the Revitalize Scalp Serum: a few drops after showering, left in.
Can a deep conditioner repair split ends?
No. It can make hair softer, smoother and easier to detangle, which reduces further snagging, but a split end stays split until it's trimmed.
Do I still need a leave-in if I use a mask?
Yes, they do different jobs. The mask is a rinse-out treatment. The All-In-One Leave-In Conditioner stays in damp hair before styling and adds heat protectant, detangler and frizz control.
Is the mask rinsed out, and what about the scalp serum?
The mask is rinsed out after 5-10 minutes. The Revitalize Scalp Serum is not rinsed. Massage a few drops into the scalp after showering and leave it in.
