"I usually don't leave reviews but I fell in love with these products.


The Curl Cream is super moisturizing. I use it right after washing while their hair is still damp, and it brings their curls to life!!!

The Curl Enhancing Jelly defines their curls beautifully and keeps them frizz-free all day.

I know it is a kid's product but I use it too! I have curly hair myself, and I honestly love how these products work on my hair just as much as my kids’. It’s hard to find something that works for all of us – but this does.

I like the fact that it's made with real flaxseed extract and no harsh ingredients. It smells great and just works. We’re officially a Sir Flax family!"

How to Take Care of Kids’ Curly Hair | Sir Flax Guide

Curly hair can be absolutely beautiful on kids, but it can also be dry, tangle-prone, and overwhelming, especially for parents who didn’t grow up with curls themselves. The good news: with the right routine and kid-friendly products, caring for your child’s curls can become a calm, confidence-building part of your week.
Why You Should Use Natural Hair Products on Your Kids

Why You Should Use Natural Hair Products on Your Kids

Every parent knows that bath time, hair styling time, and washing time can be anything but pleasant with growing kids. They want to do things their way, not always understanding the importance of personal hygiene and taking time to style one’s hair. Even worse, many synthetic products on the market can be harmful to your kid’s health, skin, and hair follicles. That’s why you should make a commitment to use only natural hair care products for your kids. Here are a few reasons to consider: Reason #1: Chemical-Free A plethora of hair products contain chemicals such as sulfates and parabens that have been attributed to hair loss, premature aging, and even worse, cancer. Such elements can be absorbed by your kids’ scalps, endangering them and their health as they age through their teen years. With natural hair products, such risks can be minimized. Reason #2: No Animal Cruelty Many all-natural hair care companies are committed to no animal testing. That means you will be using cruelty-free products when you wash your kids’ hair every night. Reason #3: More Sustainability Teaching your kids at a young age to be kind to the planet and sustainable in their consumption is so important. Many natural hair products have a biodegradable composition that supports the goal of being kinder to the planet. Reason #4: Healthier Hair You want to ensure your kids’ hair products are not interfering with their hair follicles or hair beds. By protecting the integrity of the keratin in their hair, they are more likely to reach adulthood with thick, fortified hair that is natural, healthy-looking, and beautiful. Reason #5: Safer Hair is connected to our scalp where it receives vitamins and nutrients from our blood. As a result, harmful chemicals you put on your scalp can go into your body and wreak havoc on your blood and organs. The same holds true for your kids. That’s why you want to ensure you use natural hair products for kids that rely on Mother Nature’s pristine ingredients in the composition of their formula. Safe, Natural Sir Flax Products For Kids Know that natural hair care brands like SIR FLAX are committed to organic, natural, vegan, and cruelty-free formulas. Be sure to check out our SIR FLAX PRODUCTS made just for curly kids, helping them to look and feel good in the skin they’re in. Not to mention, it’s better for their health – what more could you want as a parent?
What I Wish I Knew About Curly Hair Products for Kids

What I Wish I Knew About Curly Hair Products for Kids

There are certain pieces of advice you hear everywhere when you’re a new parent: how to get your child to sleep, when and what to feed them, and how to discipline them. But when it comes to managing your child’s beautiful but chaotic curls, everyone is suddenly silent. In many families, straight-haired and curly-haired parents alike find themselves confused and overwhelmed when trying to keep their child’s hair in check. Why is it so difficult to manage your child’s curly hair, and how do you find the right curly hair products for kids? Why Caring for a Child’s Curly Hair Is a Challenge It’s no secret that caring for curly hair is more complicated than straight hair. The hair itself is tricky, but when it’s attached to a child, you reach a whole new level of difficulty. Maintaining the Moisture Balance Hydration is one of the most important aspects of managing curly hair. Curly hair tends to dry out more quickly than straight hair, and that dryness leads to epic levels of frizz and breakage.   As challenging as it is to keep an adult’s curly hair hydrated, it’s far more difficult with kids. They’re running and playing outside, and they may need baths more often than their hair needs to be washed. And when swimming season comes around, all bets may as well be off. Harsh Products Products for curly hair are notorious for containing chemicals to keep the hair under control. Those products are especially irritating to a child’s delicate scalp.   In most cases, kids don’t love the way those chemicals smell, either, so you won’t exactly have their full cooperation during your styling sessions. Furthermore, it’s important to avoid getting the chemicals into your child’s eyes, which is difficult when they’re squirming around, trying to get back to playing. Time, Time, and More Time   Curly hair takes more time to manage, and if there’s anything that a parent doesn’t have, it’s extra time. Especially if you’re using separate products for conditioning, frizz control, strengthening, and curl enhancement, you’ll have a tough time fitting it all into your schedule. Tips for Caring for Your Child’s Curly Hair As complex as curly hair might be, it’s truly beautiful when you establish a routine and find the right products to manage it. A few handy tips can give you more control. Keep Shampoo to a Minimum As important as it is for your child’s hair to be clean, shampoo will also cut down on the hair’s natural moisture and make your child prone to frizzy tangles. The goal is to shampoo your child’s hair as little as possible.   Every person’s hair and scalp is different, so it will take some experimentation to see how long you can wait between shampoo sessions.   Between shampoos, you can wash your child’s hair with water and conditioner alone. Your routine may vary, but many parents only need to shampoo once per week while washing and conditioning the hair every few days. Stick to Products with Natural Ingredients As common as harsh chemicals are in curly hair products for kids, they aren’t inevitable. Seek out products that use natural ingredients instead.   This allows your child to avoid uncomfortable scalp irritation and it cuts out the potential dangers of using the hair care chemicals long-term. As an added bonus, taking away the strong chemical smell means your child may have more patience for the process. Detangle the Right Way Detangling a child’s curly hair after bath time has caused stress for countless parents, not to mention pain and annoyance for their kids. While it takes time to learn the technique, one of the most common mistakes to avoid is detangling from the roots down.   Instead, start at the ends of your child’s hair and detangle small sections at a time, working your way toward the roots. This is more efficient and it reduces breakage.   Be Careful with Breakage   Speaking of breakage, this is a major issue for anyone with curly hair. Not only is curly hair more prone to breakage because it’s dry, but the breakage leads to a level of frizz that straight-haired people couldn’t imagine.   It’s important to be gentle with your child’s hair.   You’ll also need to be cautious with hairstyles. Look for headbands and ponytail holders that are made for curly hair so they don’t get tangled as easily. What Makes Sir Flax Different from Other Curly Hair Products for Kids I speak from experience when it comes to curly hair products for kids and the challenges they present. That’s why I developed a product that addresses those issues to make life easier for parents and kids.   Sir Flax is a multi-action product, providing frizz control and curl enhancement while also strengthening the hair against future breakage. This means fewer products to buy and less work to squeeze into your schedule.   Most importantly, though, Sir Flax uses exclusively natural, organic ingredients that will be gentler on your child’s sensitive scalp in the same way they relieved my own son’s scalp irritation. Getting the Products You Need for Your Child’s Hair Curly hair has a beautiful uniqueness that every child should feel proud to wear. As a parent, when you learn how to keep those curls beautiful and healthy, you empower your child to see their curls as the blessing they are.   To simplify your routine while enhancing your child’s curls, shop our Sir Flax curly hair products for kids.
