First, no sunscreen will be complete without considering the various SPF (Sun Protection Factor) ratings and the UVA and UVB ray protections some of the more common sunscreens offer. When it comes to the scalp, the sunscreen should offer a reasonably high SPF — at least 40, if not higher — to ensure the best memorialization against the suns rays. Additionally, the sunscreen should offer full spectrum UVA and UVB protection, as both of these types of rays can cause a range of issues on the scalp, such as premature hair thinning, skin ageing and an increased risk of skin cancer.
The formulation of the sunscreen also makes a difference, as different ingredients offer various levels of protection. Generally speaking, sunscreen formulas that contain Vitamin A, Vitamin E, Niacinamide, green tea extract, coffee extract, licorice extract and other antioxidants are recommended as they offer the scalp both protection from the sun's rays and nourishment for the hair. To further bolster hair and scalp protection, look for sunscreens that contain safflower seed oil and green tea oil as these natural oils provide additional nourishing and emollient properties, while offering added protection against dehydration.
For those who suffer from thinning hair, a specialty sunscreen formulated specifically for the scalp and hair may be beneficial. That’s because, in addition to protecting the hair and scalp from the sun, these products deliver additional benefits such as lift and volume. With proprietary technology, these sunscreens add body to the hair, giving it a healthier, more voluminous look.
Finally, it's important to opt for sunscreens that use only safe and effective UV active ingredients, such as homosalate, octocrylene, octisalate, avobenzone. These ingredients provide maximum protection against the sun, while being gentle on the scalp and hair.
As with all sunscreens, it's important to apply and reapply as directed. Reapplication every two hours is generally recommended if you plan on spending extended amount of time under the sun.
There is a wide variety of considerations to take into account when determining how to best apply sunscreen to the scalp. These considerations include the sun protection factor rating, the type of UVA and UVB protection the sunscreen provides, the formulation and ingredients, whether to use a regular sunscreen or one specifically designed for the scalp and hair, and the type of UV active ingredients. By making the right choice, you can protect your scalp and hair from the damaging effects of the sun and, at the same time, enjoy the feeling of having voluminous, healthy locks.
