The 3-in-1 Leave-In Conditioner Made For Beach Days

Coconut oil, banana extract, and sunflower seed oil might sound like the ingredients for a tropical smoothie, but they’re actually the main ingredients of Sun Bum’s Revitalizing 3 In 1 Leave In Conditioner that’s gone viral on TikTok.

The formula is designed to detangle, nourish, and shield hair from UV rays, making it a beach bag essential, whether you are going to dip your toes in the sand or recline by the pool. But while it is primarily designed for sun-soaked exploits, we’re making a case for year-round use on account of its versatility and lightweight finish.

Born out of California, Sun Bum has built its reputation on protecting both the skin and hair from UV rays, and this leave-in conditioner is one of its bestselling products. Suitable for all hair types, it’s one of those haircare heroes where after you try it once, it will become a permanent fixture.

Made up of naturally-derived conditioning ingredients, the aforementioned coconut oil, banana extract, and sunflower oil take a starring role. But the trio is enhanced by the inclusion of argan oil and watermelon seed oil; plant-based oils which are an excellent source of fatty acids to nourish hair, improve softness, and enhance shine.

Banana extract imparts vitamins and minerals, while squalane locks in moisture and maintains hydration. The formula also includes two well-known haircare ingredients: glycerin, which attracts and retains moisture, and panthenol (pro-vitamin B5), known for strengthening and smoothing the hair fiber. To complete the blend, hydrolyzed quinoa helps to reinforce hair and improve manageability.

The three-in-one benefits refer to the formula’s detangling, nourishing, and protective qualities; but there is more. Over time and used consistently, the cocktail gradually restores hair’s natural body, while there are immediate effects, too. Hair feels noticeably smoother, looks shinier and is easier to comb through. It also controls frizz, reduces the appearance of split ends and preserves color, protecting against fading caused by salt water, chlorine, and sunlight. There are no parabens or sulfates.

For best results, spray Sun Bum’s 3-in-1 Leave-In onto wet, towel-dried hair immediately after shampooing, then comb through or quickly run your fingers through the strands. At the beach or pool, rinse hair to remove salt water or chlorine–even if you aren’t washing it with shampoo. You can also apply it to dry hair as a lightweight protective treatment. As the formula is lightweight and non-greasy, it’s suitable for daily use and won’t weigh hair down.

Application tip: focus application on the mid-lengths and ends. Avoid spraying directly onto the roots unless your hair is particularly dry, as this may leave the scalp looking oily. That being said, those with very dry, coarse, or highly textured hair may benefit from extra hydration at the roots.
