How to Repair Damaged Hair: 5 Easy Tips for Dry, Bleached Hair

This post is sponsored by Nexxus, but all opinions and experiences are my own.

If your hair is feeling dry, frizzy, brittle or just plain exhausted, girl, I’ve been there! Between highlights, balayage, hot styling tools and everyday wear and tear, even the prettiest hairstyles can leave your strands begging for a little TLC. And while we all love that fresh-from-the-salon look, keeping colour-treated hair feeling soft and healthy can take some extra effort. My hair was the longest it had ever been when I originally wrote this post, but it was also bleached to high heavens. The balayage looked gorgeous, but my poor ends were definitely feeling the effects. So I decided it was time to give my hair some extra attention and find a routine that actually worked for me. If you’re wondering how to repair damaged hair and make dry, bleached hair look healthier, I’m sharing five simple haircare tips that helped me manage frizz, improve softness and give my long locks some much-needed love. Plus, keep reading for my results after trying a 30-day Nexxus haircare challenge!

What Causes Dry, Damaged Hair?

Before we get into my favourite damaged hair treatments, let’s talk about why hair becomes dry and brittle in the first place. Hair damage can happen for several reasons, including frequent heat styling, bleaching, chemical colouring, friction and everyday environmental exposure. When the outer protective layer of the hair becomes damaged, strands can feel rougher, tangle more easily and become more prone to breakage. You might notice split ends, frizz, dullness or hair that seems harder to style than usual. Bleached hair can be especially vulnerable because lightening treatments alter the hair’s structure. Although you can’t completely reverse damage to the hair shaft, the right routine can help improve its appearance, reduce further breakage and make your hair feel softer and more manageable.

1. Use a Deep Conditioning Hair Mask Weekly

If your hair is dry and damaged, adding a conditioning hair mask to your routine is one of the easiest places to start. Between hot styling tools, bleach and everyday exposure, my hair can quickly go from silky to feeling like straw. Not exactly the look I’m going for! A good hair mask can help condition the strands, improve softness and make hair easier to detangle. I especially love using a richer treatment when my ends start feeling rough or my hair becomes difficult to manage.

How to Use a Hair Mask for Damaged Hair

Start by choosing a hair mask formulated for your hair type and concerns. Some treatments are designed to provide extra conditioning, while others focus on strengthening or reducing breakage. Follow the directions on the packaging, since not every hair mask is intended for dry hair or a 30-minute treatment. Most traditional conditioning masks are applied to clean, damp hair and left on for a specified amount of time before rinsing. I like concentrating the product on my mid-lengths and ends, where my hair tends to need the most attention. Using a hair mask about once a week can be a great starting point, although the ideal frequency depends on your hair and the formula.

2. Take a Break From Heat Styling

Okay, you’re probably going to hate this one. I know I did! As someone with super long hair, I understand the temptation to grab a hairdryer and get the whole process over with. Air-drying can take forever, especially when you have thick or lengthy locks. But when my hair is feeling particularly fragile, reducing how often I use hot styling tools makes a noticeable difference in how manageable it feels. Frequent exposure to high temperatures can contribute to dryness and breakage, particularly when hair is already chemically treated.

3. Sleep on a Silk Pillowcase to Reduce Friction

Let’s talk about one of my favourite little beauty upgrades: a silk pillowcase! If you’ve ever woken up with a serious case of bedhead, you know how frustrating it can be to spend time styling your hair only to have it look completely different the next morning. Silk has a smooth surface that may help reduce friction between your hair and pillowcase while you sleep. Less friction can mean fewer tangles and less pulling, which is especially appealing when you’re trying to be gentle with fragile or bleached hair.

4. Get Regular Trims to Remove Split Ends

I know, I know. When you’re trying to grow long hair, the last thing you want to hear is that it’s time for a haircut! But here’s the thing: keeping damaged ends doesn’t actually help your hair look healthier. Over time, split ends can make hair appear frizzy, uneven and less polished. And unfortunately, once a strand has split, no shampoo, conditioner or leave-in treatment can permanently fuse it back together. Products can temporarily smooth the appearance of split ends, but trimming is the reliable way to remove them.

5. Find a Shampoo and Conditioner That Work for Your Hair

You know that saying about finding a good thing and sticking with it? I think the same idea applies to haircare. While I love trying new beauty products, there’s something to be said for finding a shampoo and conditioner that leave your hair feeling clean, soft and manageable. And when my bleached hair was feeling particularly dry and frizzy, I decided to give my routine a little refresh.

My 30-Day Nexxus Haircare Challenge

As you guys know, I was challenged by Nexxus to use their haircare products exclusively for 30 days. Since my hair was long, colour-treated and in desperate need of some extra attention, I was excited to see how the products would work for me. During the challenge, I washed my hair approximately every three to four days using Nexxus Therappe Shampoo and Nexxus Humectress Conditioner. I also incorporated Nexxus Promend Leave-In Crème for Hair Prone to Split Ends into my routine.

One of my biggest concerns at the beginning was frizz. My hair could be difficult to manage, particularly after washing and styling, and I wanted it to look smoother without feeling weighed down. I also tried Nexxus Frizz Defy Finishing Mist, which quickly became one of my favourite products from the experience.

My Nexxus Haircare Results After 30 Days

So, did the challenge actually make a difference? For me, yes! After 30 days, my hair felt noticeably softer and silkier, and I found it easier to style. It also looked less frizzy than it had at the beginning of the challenge. The Frizz Defy Finishing Mist was especially helpful for managing flyaways and creating a smoother-looking finish. I enjoyed using the Therappe Shampoo and Humectress Conditioner together because my hair felt more conditioned and manageable.

How to Keep Bleached Hair Looking Healthy

If you love highlights or balayage as much as I do, you don’t necessarily have to give up colour to improve your haircare routine. The goal is to be a little more intentional about how you care for your strands between salon visits. I like focusing on gentle detangling, conditioning treatments, reducing unnecessary heat and getting trims when my ends need attention. If your hair is severely damaged, breaking easily or feeling unusually fragile after a chemical treatment, a professional hairstylist can help assess what your hair needs. And if you’re experiencing significant shedding or hair loss from the scalp rather than breakage along the lengths, it’s worth speaking with a healthcare professional.
