Does UV Damage Hair?
Yes, UV does damage hair because it penetrates deeper into the curls, weakening the hair shaft, leading to breakage.
There are two main types of UV rays: UVA and UVB. Curly hair is prone to dryness, and UVA rays penetrate deeper into the hair fiber, weakening the hair shaft and stripping curls of their natural oils, making them more brittle and prone to breakage over time. UVB rays act more on the surface, damaging the cuticle and contributing to protein loss, which can reduce strength and elasticity over time. The UV index, which ranges from 0 to 11+, helps indicate risk levels for your curls, 0-2 is low risk, 3-5 can cause gradual dryness, and 6+ may lead to significant UV damage without protection.
Which UV Levels are Safe for Curls?
According to the UV index and hair safety guide for curly hair, a UV level of 0-2 is considered safe. There is a minimal risk of UV damage and no protection is required. UV levels 3-5 are somewhat safe for your curls but you might notice that they’ve become drier than usual or if you’ve dyed your hair, the color might start to fade. Although the impact is moderate compared to higher levels, using a hair product with UV protection or wearing a hat is recommended. Anything from 6+ is either high, very high or extreme.
Can UV Lighten Hair?
The sun can lighten your curls but you’ll notice this more if you have lighter hair. UV rays break down melanin, which is the pigment that gives your hair its natural color. Curly hair strands have raised cuticles so UV rays can penetrate more easily and this speeds up the lightening process, particularly on the top layers of your hair and any outer curls that are exposed to light.
Does UV Cause Hair Loss?
No, UV exposure doesn’t directly cause hair loss from the root. However, it can damage the hair shaft, weaken strands and lead to breakage, which may appear as hair loss. True hair loss occurs when hair sheds from the follicle, not when strands snap due to sun-related damage.
3 Signs Hair is Damaged by UV
So, you may be wondering how to tell if your hair is damaged due to UV rays. Keep reading to see if you recognize any of the following signs your hair is damaged.
Excessive Dryness
UV rays dry out curls by damaging their structure and depleting it of moisture, which is something that curls can lose easily. As curly hair relies on moisture in order to thrive, the biggest giveaway will be curls that remain dry no matter how you try to repair the issue.
Loss of Elasticity
When UV rays break down the hair’s proteins and lipids, a loss of elasticity and overall hair health occurs. There are some signs of elasticity loss to look out for if you suspect your hair has been damaged by UV including increased breakage or split ends, a lack of stretch and a loss of curl pattern. The good news? With the right strengthening hair products this damage can be addressed to help your curls bounce back.
Increased Frizz
If you find that your curls are very frizzy, particularly after spending time in a hot or humid environment, then they might have been damaged by UV rays. Frizz is a result of dryness and an imbalance of moisture but there are some other signs that you’ll want to look for including increased tangles and knots and dullness or a loss of shine. Using frizz control products designed for curly hair will help to tame unwanted frizz
4 UV Protection for Curly Hair Tips
Now you know the signs, you may have realized that your hair is affected by UV damage, or perhaps not. Either way, keep reading to learn summer curl care tips to help prevent UV damage and protect your curls.
Moisturize Hair Regularly
UV damage can quickly strip curls of their natural moisture, making regular hair hydration especially important during summer months or on high UV days. When curls become dehydrated, they’re more prone to dryness, breakage and loss of definition, which is why knowing how to keep curls moisturized is key. Supporting your routine with intentional moisture makes all the difference, and this is where deep conditioners come into play. The Curlsmith Double Cream Deep Quencher helps replenish lost moisture, while the Multi-tasking Conditioner helps to moisturize and strengthen the hair after sun exposure.
Limit Time Spent in the Sun
In the US, the climate tends to differ. The East Coast is colder than the West Coast although it brings hotter air in the summer. The West Coast is milder with warm, dry summers and mild, wet winters. In the UK, there is a shorter summer window as warmer periods tend to vary throughout the year. When it comes to understanding the impact that the climate could be having on your curls, it can be helpful to know what the peak sun hours are and avoid being in the sun during these times. The same principle applies if you’re on holiday. If you are going to be outside on a warm day, then wear a hat or a scarf to block UV radiation, reduce heat exposure and shield your curls against wind and pollution.
Try a Protective Style
Protective curly hairstyles for hot weather like braids, twists and cornrows are a great way to help shield your curls from UV exposure by keeping strands tucked away and less exposed to the elements. They can also help retain moisture by reducing daily manipulation and supporting the distribution of your hair’s natural oils down the shaft. If scalp protection is a concern, protective styles offer an added layer of defense against sun exposure, and they pair perfectly with outer protection, especially if you’re learning how to wear a hat with curls.
Use UV Protection Hair Products
For extra support, pairing your style with UV protectant for curly hair is key. A lightweight spray like Curlsmith Miracle Shield can easily be applied to both the hair and scalp, even while in a protective style, alternatively a curl cream with UV protectant is perfect for coating the strands with moisture and protection before styling.
UV protection for curly hair is often overlooked, but it plays a key role in keeping curl’s healthy and strong. Sun exposure can dry the hair, increase frizz and weaken strands over time. Understanding how UV affects your curls makes it easier to protect them with the right care habits and routine. Choosing well formulated curly hair products that support moisture, strength and protection can help your curls stay well balanced and defined in the sun, whatever the season.
