Summer Hair's Best Friend

We love summer, but let's be honest, summer can be tough on our hair. Chlorine from pools is notorious for stripping away natural oils, leading to dryness, breakage, and even color fading. Saltwater has a similar effect, pulling moisture from your strands and leaving them rough, tangled, and prone to frizz and split ends. Add in strong UV sun exposure and layers of styling products and your hair might end up dull, heavy, or brittle from all that buildup. Traditional shampoos can sometimes feel too harsh when used frequently, especially if you're trying to preserve a color treatment or maintain your hair’s natural moisture balance. In short, the summer hair struggle is real, and our strands are carrying a lot of baggage by season’s end.

What Makes Lost Treasure Special

This is where LOST TREASURE APPLE CIDER VINEGAR CLEANSING RINSE comes in as a game-changer. It isn't your typical shampoo or conditioner but a cleansing rinse designed to detox your hair without stripping away your natural oils or color. It is formulated to gently cleanse away product buildup and impurities while helping maintain your hair’s optimal pH balance. The result is hair that feels refreshed but not "stripped", softened, calmed at the scalp, and left with dramatic shine. Regular use even strengthens your hair over time thanks to fortifying ingredients in the formula.

The magic lies in its key ingredients and a cocktail of hair-loving compounds. This rinse is sulfate-free, vegan, and infused with soothing botanicals like aloe vera and tamanu seed oil. Aloe vera provides moisture and anti-inflammatory benefits to help reduce scalp irritation, while tamanu oil (traditionally used in Polynesian hair care) can help calm an irritated scalp and even has antimicrobial properties. In other words, Lost Treasure manages to be both gentle and effective, a rare combination. You can use it as an occasional deep clarifying treatment when you need a reset, or incorporate it into your regular routine for continuous maintenance without fear of over-drying your hair.

Perfect for Post-Beach or Pool Hair

One of the best times to use Lost Treasure is after a day at the beach or pool. If you've just spent hours in saltwater or chlorine, this rinse is exactly what your hair needs as salt can leave your hair sticky, tangled, and dull, and chlorine can wreak havoc on color-treated hair (sometimes even giving blondes that unwelcome greenish tint). Lost Treasure gently removes these impurities and any crusty salt or chemical residue without the harsh stripping that many clarifying shampoos have. This means you get rid of the gunk but keep your hair's natural moisture intact, avoiding that dry, brittle feeling.

The Apple Cider Vinegar Advantage

So, what’s the secret sauce in Lost Treasure that makes it so special? It’s apple cider vinegar (ACV), a time-honored beauty secret turned modern haircare hero. ACV acts as nature's gentle reset button for your hair and scalp. Hairstylists and trichologists praise ACV for its abundant benefits, not dismissing it as just a wellness fad. In fact, R+Co’s own expert, Adam Federico, says that “apple cider vinegar is wonderful in so many ways. It leaves hair looking healthy and shiny, and restores balance to an irritated scalp.”

What else can ACV do? Let’s break it down

ACV clarifies without over-drying. Its natural acids gently break down and dissolve build-up from oils, styling products, and minerals. It balances scalp pH and soothes irritation. Our scalp’s natural pH is slightly acidic, which keeps the cuticle layer of hair closed and healthy. Thanks to its anti-inflammatory and antimicrobial properties, ACV can calm itchiness and reduce flakes on the scalp. If your scalp gets cranky from sweat and product buildup in summer, ACV is like a calming tonic.

It also adds shine and protects color by smoothing and sealing the hair cuticle. When the cuticle is flat and closed, it also locks in color for those with dyed hair, preventing color fading. The enzymes from fermented apples help close that cuticle layer, which in turn preserves moisture and color molecules inside the hair shaft.

By helping to smooth the cuticle, it reduces frizz and flyaways (raised cuticles are why humidity causes frizz). A nice side benefit of this cuticle smoothing is easier detangling so hair feels more manageable and combs through with less snagging.

ACV also helps support strong and healthy hair. While ACV itself isn't a protein treatment, using it to keep the scalp clean and balanced means your roots can breathe and your conditioning products can penetrate better once buildup is gone. Lost Treasure’s formula even includes a plant-based protein and conditioning agents that help reinforce the hair.

In short, the ACV advantage is that you're giving your hair a deep yet gentle clean and a dose of scalp therapy all at once. It’s like hitting the reset button on your hair, but without any damage or drama.

How to Use It

One of the best things about Lost Treasure is how simple it is to use. You don't need to overhaul your routine, just swap it in when needed. Here’s how to get the most out of this cleansing rinse.

Start with Wet Hair

In the shower, wet your hair thoroughly with warm water (warm water helps open up the cuticle and loosen any debris).

Apply to Scalp

Using the bottle's pointed tip, gently squeeze the Apple Cider Vinegar rinse directly onto your scalp in sections. Focus on the areas where you have buildup (like the crown or hairline). The nozzle makes it easy to apply precisely at the roots.

Massage and Wait

Massage the rinse into your scalp and work it through your hair from roots to ends. You’ll notice the watery-liquid formula distributes easily. Let it sit for 1–3 minutes. This gives the ACV and other ingredients time to break down oils and impurities.

Rinse Thoroughly

Rinse out the product well with water, making sure to flush away all the loosened build-up. You can follow up with your favorite conditioner on the ends if you want extra softness, but many people find they don't even need a conditioner after this rinse because hair is so smooth.

Use as Needed

You can use Lost Treasure in place of your shampoo on days when you want a gentler cleanse, or even instead of a conditioner if you’re a co-wash devotee. For most, using it about once a week or every few washes is perfect to keep hair clarified and balanced. After lots of swimming or heavy product use, it's the ideal reset. Always adjust frequency based on what your hair likes. Even though it's gentle, you might not need to use it every single day.

And a little goes a long way. Because it's liquid and spreads easily, you don't need to squeeze out half the bottle. A few targeted squirts will do. As you massage, you'll feel your hair getting clean (without that squeaky stripped feeling).

Whether your hair is recovering from summer adventures or you’re simply craving a scalp reset, LOST TREASURE APPLE CIDER VINEGAR CLEANSING RINSE might just become your new go-to. It tackles the summer hair struggles (and year-round buildup issues) in one swoop: clarifying, softening, soothing, and shining up your hair all at once. Best of all, it preserves the things you love about your hair such as your color, your natural oils, and your texture while removing the things you don’t.
