All you have to do is walk down the hair care aisle of your local beauty supply store and you’ll find dozens of products lining the shelves claiming to “repair damage”—but is that even possible? To find out, we sat down with Ashley Brown, Mizani artist, educator, and brand ambassador who told us everything we’ve ever wanted to know about damaged hair and whether it’s possible to repair damaged hair once and for all.

How does hair become damaged?

Unfortunately, there are many ways for hair to become damaged, but Brown breaks down the most common causes of damage as follows:

- Mechanical damage.

This can happen if you mishandle fragile tresses by brushing too hard or pulling your hair too tight.

- Neglect.

If you’re not paying attention to your hair’s texture and major concerns (i.e. dryness or environmental changes) chances are good that your hair could experience damage.

- Thermal damage.

This kind of damage can happen when hot tools are used too frequently, at too high of a temperature setting, or without the proper heat protection.

- Chemical damage.

Whether you’re using hair dye, relaxers, or trying out a perm, all chemicals services can cause damage.

- Overall health.

Sometimes medications and illnesses can compromise the health and integrity of the hair. If you have additional questions about this, consult with your doctor.


The big question is this: Can damaged hair be repaired?

Damaged hair if addressed early enough, can sometimes be repaired with the proper plan of action.

“If you see stress or feel dryness on your ends as a result of mechanical or thermal damage, trimming the ends more frequently, deep conditioning your hair on a more regular basis, using the proper tools, and heat protection products will vastly increase the likelihood that your damage can be [minimized].”

However, Brown says you may need to take more drastic measures if a botched chemical treatment damages your hair.

“If your hair has chemical damage, evaluating the chemical services being done and deciding whether or not to take a break from them and step up your care routine by deep conditioning more frequently (and using a more intensive product) may allow you to begin to repair the damage.”

Unfortunately, there is one kind of damage that can’t be repaired: split ends.

“Once the hair strand has begun to split, it can sometimes be temporarily mended. But ultimately, it just needs to be cut off,” the stylist explains. “If the split ends are not cut off, they can and will continue to split up the hair shaft leading to more severe damage and breakage.”

Prevent damage before it happens.

The best way to avoid damaged hair, is to prevent damage before it even happens. Brown insists the most important thing you can do is seek professional help.

“Consulting with [a hair professional], especially one who caters to a clientele with similar hair needs to yours, is very crucial,” Brown says. “They will be able to give you the tools and the advice you need to maintain your look and stop damage from the start.”

Not only will a professional be able to help you achieve your hair goals with minimum damage, but also they will recommend against services that have the potential to wreak havoc to your locks. Not all hair services are created equal, so if your stylist advises against something believe them.

Furthermore, professionals have spent years learning and perfecting their craft. If you’re concerned about the health of your hair, skip the DIY treatments and find a stylist you trust.

“Always have a licensed professional perform any and all chemical, cutting, or styling services to ensure they are being done with a high level of integrity,” Brown says. “Be your own advocate and research the professional before you sit in their chair. Ask yourself, do they currently have guests who may be suffering from similar hair needs as myself?”

Caring for your hair at home.

After you’ve found a hair care professional you trust, it’s time to work on your hair care routine. Your stylist should be able to recommend the right products and routine for your hair, but there are some hair care basics everyone should follow.

“Industry standards suggest getting regular trims every four to six weeks (this may vary depending on the needs of your hair),” Brown says. “It is also important to use the proper system of professional shampoo, conditioner, and a treatment for your specific hair needs at home in between salon visits.”

Brown’s next tip for preventing damage before it happens is the easiest one yet: Pay attention to your hair!

“Be alert. It is so easy for us to be on autopilot and sometimes our hair can begin to show signs of damage before we truly realize it,” Brown explains. “Adjusting your routine to accommodate for small inconsistencies that arise with your hair can work wonders in the big picture.”

Everybody’s hair care routine should include shampoo, conditioner, deep conditioner, leave-in, and styling products. If you’re not sure where to start, Brown has a few suggestions.

“My go-to products...are those in the Mizani Thermasmooth line,” the stylist says. “With a balance of protein and moisture, the shampoo and conditioner set the hair up for success. The Mizani Thermasmooth Sleek Guard is another favorite of mine for heat styling.”

If you’ve got your hair care routine down pat but are still looking for a product to give your hair a little extra TLC, look no further than Mizani’s 25 Miracle Milk. It’s one you’ll certainly want to add to your product arsenal.

“The Mizani 25 Miracle Milk is a staple of mine to help detangle the hair and prepare it to be styled. With 25 different benefits, it does many things to ensure the smoothness of all hair textures—heat protection and strengthening are a couple of my favorite benefits.”

If you follow Brown’s simple tips you won’t have to worry about repairing damaged hair, because your hair will be in tiptop condition!
