Even if you make your best efforts to stay away (or let's be real, cut back), from using heat tools, chemical treatments, or color, there are so many ways we put our hair through the wringer that aren't as obvious; from brushing too harshly or friction from a scratchy towel, to the literal air pollution outside and flat-out neglect from an unavoidably busy schedule.

Maybe you're not able to pinpoint where frizz, split-ends, or breakage are coming from, but when dealing with those issues, the most important piece of the puzzle is just finding a solution. Thankfully, there are a lot of answers to the question, "How do I fix my damaged hair?" But one of the easiest, most affordable, and time-saving options is to find the right reparative shampoo for you.

With so many options, though, where do you even start? To save you some time and effort, we researched the best shampoos for every type of damage and every hair type, evaluating them based on their formulas and ingredients. Our favorite is the Olaplex No.4 Bond Maintenance Shampoo because it repairs hair from the inside out, prevents frizz, and works on all hair types.

Here are the best shampoos for damaged hair.

Best Overall

Olaplex No. 4 Bond Maintenance Shampoo

You've probably heard of this miracle product by the popular brand Olaplex. But if you haven't, Olaplex No. 4 Bond Maintenance is a multi-step system that works to both prevent breakage and repair broken bonds in the hair strands on a molecular level. It truly brings hair back from the brink and leaves it smooth, manageable, and healthy. The ultra-moisturizing formula also protects hair from common woes like split ends and frizz. It promises to strengthen all hair types and it works especially well on color-treated hair. Note: overusing it may cause the hair to shed with time, so it is best to use only a dime sized amount if shampooing daily or to alternate days if your hair is on the thin side.

Free of sulfates, it features a highly concentrated formula infused with jojoba, green tea, and sage to strengthen, repair, and protect hair against breakage. Maybe most importantly for those with colored hair, it'll protect the color vibrancy and keep hair soft, so you don't have to worry so much about "straw-like" strands.

Best for Split Ends

It's all in the name with this option from Redken. The All Soft Mega Shampoo is formulated with a nourishing, unique punch of cactus extract to hydrate and add shine, aloe vera to strengthen and condition, and sacha inchi oil to help retain moisture, which leaves the hair feeling softer and more manageable. The formula also features Redken's innovative Root Core Tip protein complex, a blend of three proteins designed to zone in on and treat damaged hair where it needs it most, zipping up split-ends for full, healthy strands. It's a multi-benefit shampoo without a doubt, not only softening each individual strand and adding hydration to dry, coarse hair, but also stimulating the scalp and keeping frizz down to a minimum. What more could you want?

Best for Relaxed Hair

Carol’s Daughter Monoi Repairing Shampoo

This coconut-derived shampoo is popular for a reason: It's packed with all of the right anti-breakage heroes, like monoi oil and vitamin E, to satisfy the most delicate, fragile hair. On top of having zero sulfates, hibiscus extract works to detangle raveled tresses while coconut surfactant gives every strand a deep, deep cleanse. Together, these ingredients heal damaged hair by stopping protein loss, resulting in almost no hair breakage; and with its hydrating and soothing properties, it helps the hair become even stronger after repair. For anyone with relaxed hair — for whom brittle, breakage-prone hair is a major concern — this shampoo is a must-have.

Best for Thick Hair

R+Co Atlantis Moisturizing Shampoo

Thicker strands need a lot of moisture — and we mean a lot — on a daily basis. But when damage comes into the picture, that moisture level needs to be doubled. With this vitamin B5-enriched formula from R+Co, thick, coarse, and extremely dry hair is blanketed in an intense wave of hydration that penetrates deeply into the shaft. The glycerin gives it an extra kick of moisture, which helps prevent future dryness down the line. As if it couldn't get any better, the shampoo uses prickly pear stem and nettle extracts to ensure that your scalp is balanced, nourished and, of course, hydrated. The duo also tames frizz and makes your hair stronger.

It's perfect for frail, thinning, and fine hair, especially in this scalp-stimulating option from Keranique. It works to gently remove dirt, excess oils, and pollutants from the hair and scalp, all while repairing damage and adding volume.

What to Keep in Mind

Ingredients

When shopping for a damage-reversing shampoo, pay close attention to the ingredients. Protein-rich formulas that contain fortifying ingredients like keratin, biotin, and vitamin B5 will help strengthen brittle strands from root to tip, which is important for preventing breakage and getting your hair back on a healthy path. Since damaged hair is often dry, you may also want a shampoo that packs a moisturizing punch with hydrating ingredients such as coconut oil, jojoba oil, and olive oil. These are great for boosting shine and softness as well, which frizzy hair types will drink up.

Color-Safe Formula

If you regularly color your hair, don't choose a formula that contains damaging ingredients like sulfates, silicones, phthalates, or parabens because these chemicals are known to strip away at your color.

Hair Type

No matter what damage you may be dealing with, it is still important to buy a shampoo that is formulated for your specific hair type. If you have fine or oily hair, you'll want a shampoo that gently repairs hair, but isn't too strong or heavy. For curly or textured hair, make sure your shampoo has your luscious locks in mind.

Your Questions, Answered

How do I know if my hair is damaged?

You certainly do not need to be a hair expert or a professional to spot the signs of damage. Matt Swinney, Global Creative Director of RUSK Hair Care, explains that there are many telltale signs of damaged hair. "Damaged hair is often dull and lacking shine. It will look and feel fragile, often have breakage, and the hair will be more porous and difficult to blow dry," he says. Be on the lookout for these irregularities and if you spot any, you'll know it's time to get to work on repairing your locks.

Why is my hair damaged?

There are many causes of hair damage and sometimes, damage is just inevitable. However, you should definitely try to minimize your risk of damage as much as possible to keep your hair healthy. "The major causes of damage to hair are over processing with bleach, excessive heat styling, over texturizing while cutting and an overuse of keratin based products," Swinney says.

How often should you shampoo damaged hair?

While you may be tempted to shampoo more often in an attempt to save your hair, over-washing can actually cause more hair damage and irritate the scalp, which is probably already pretty dry. According to Swinney, it is best to shampoo damaged hair a maximum of two to three times a week. He also notes that the frequency of your shampoo will depend on the "type of damage you have and the product you are using." Always look at your specific product's recommendation for frequency and if you are unsure what type of damage your hair may be suffering from, try consulting with your hairstylist.
