Hair Dye, Tooth Gems And Piercings: When’s The Right Age?

Once children start experimenting with the way they look via hair dye, tooth gems and piercings, when is the recommended age for them to start?

Remember the days when your little ones were happy to wear anything you picked out for them? Fast forward a couple of years, and now they have a mind of their own when it comes to appearance. This can include embellishments like nail polish, as well as experimenting with more permanent options like dyeing their hair or rocking tooth gems.

As parents, our job is determining the most appropriate age for self-expression to take place. While there are no hard and fast rules (and it varies with each individual) here’s a rough guide on the optimum time to start giving free rein.

Is Hair Dye Appropriate For Kids?

Really, what’s the rush? Recent 2025 studies highlight growing concerns about children’s exposure to hair dye chemicals, linking them to skin reactions, hormone interference and even potential cancer risk. If your child insists on a new hair colour, consider temporary natural dyes comprising coffee, as well as lemon, carrot or beetroot juice.

Sassy Tip: Do the patch test to find out whether your child is allergic. Apply the dye on a small area of their skin, and see if any reaction occurs. If nothing happens, go ahead and apply. However, stop immediately if you notice rashes or hives popping up!

Are Tooth Gems Safe For Teeth?

Purely aesthetic in nature, and seen on celebrities like Rihanna, Hailey Bieber, and Katy Berry (and well loved by teenagers) tooth gems offer bling for teeth, a look that gives plenty of personality. The gems are attached to the teeth using special dental glue and don’t require invasive procedures like drilling.

While there’s no age restriction for tooth gems, kids under eighteen need parental consent. They are not recommended for younger children whose jaw and teeth structure are still developing.

It’s also pertinent that your child can independently upkeep their dental hygiene. If food is caught around the gem and becomes stuck, this can lead to tooth decay. There’s also a risk that the enamel (outer layer of the tooth) may become damaged over time with repeated applications of the dental glue. If the gem detaches, it may also pose a choking hazard for younger children.

Sassy Tip: If your child is an avid sports player or martial arts fighter, consider investing in a mouthguard to prevent any injury caused by the tooth gem.

How Young Is Too Young To Get Piercings?

It’s worth noting that many parents choose to have their children’s ears pierced at a young age — a common cultural and personal tradition that’s generally safe and far from the ‘traumatic’ or ‘mutilating’ label some Mama blogs may suggest. It’s important that piercings are looked after, either by a caregiver or the child. Without proper care, they can be prone to infection. When it comes to more complex nose, navel or helix ear piercings, consider waiting until the child is older.

Sassy Tip: Take the time to explain the risks of piercings to your child. Many kids love the look of piercings but may be unaware of the consequent care required.

Go With Non-Permanent Options Instead

That being said, mamas, if your child has been expressing interest in getting any of the above options, don’t worry! In fact, there are plenty of other ways for kids to experiment with beauty or jazz up their appearance without using permanent options.

Some alternatives include hair tinsel, hair extensions, hair chalk, face gem stickers, as well as nose piercing stickers, faux rings, clip-ins and nose cuffs. This is especially so for school-going kids and teens, so as to avoid getting into trouble with Hong Kong’s school uniform rules. Non-permanent embellishments are the way to go, at least until they graduate! Otherwise, makeup can also be a fun, creative outlet for kids to explore and express themselves.
