Know Your Hair | Beach Water Spray Hair Guide
Every hair type behaves differently in ocean water. Fine hair gets lift and texture without weight. Thick hair gets definition without crunch. Wavy hair gets pattern without collapse. Beach Water Spray has three formulas — each drawn from a different ocean source, each calibrated for a different hair type. This is where you find yours.

Beach Water Spray Hair Guide
Most sea salt sprays are designed for one idealized hair type. Beach Water Spray isn't. The three formulas below correspond to real differences in hair density, porosity, and wave pattern. Find the descriptors that match your hair, then follow the guide.

The Science
Real Ocean Water vs. Synthetic Sea Salt Spray
Most sea salt sprays are sodium chloride dissolved in tap water. Here's what makes the real thing different — and why it shows up in your hair every time you use it.

What is the difference between the three Beach Water Spray formulas?+
Each formula is drawn from a different ocean source and calibrated for a different hair type. Hawaii uses Pacific Ocean water and is designed for fine, thin, and low-density hair. Grand Cayman uses Caribbean Ocean water and is designed for thick, coarse, and curly hair. 30A Seaside uses Gulf Coast water and is designed for wavy, medium-weight hair. The mineral profiles differ by source, which is why each formula behaves differently on the strand.
How do I know if I have fine, thick, or wavy hair?+
Fine hair is about strand diameter — individual hairs are thin, hair lacks volume without product, and product tends to weigh it down quickly. Thick hair is about density and diameter — lots of hair, strands that feel substantial, and a tendency toward frizz rather than flatness. Wavy hair is about pattern — the hair naturally wants to curl or wave but doesn't have the full curl pattern of curly hair. Many people have a combination, in which case the dominant characteristic (fine vs. thick vs. wavy) is usually the right starting point.
Can I use Beach Water Spray on color-treated hair?+
Yes. All three formulas are free from sulfates and the harsh synthetic compounds that strip color. Real ocean water is gentler on processed hair than concentrated synthetic salt alternatives. If your hair is both color-treated and fine, Hawaii is the natural starting point. Color-treated thick or curly hair responds well to Grand Cayman.
Which formula holds up best in humidity?+
All three formulas hold better in humidity than synthetic sea salt sprays because the mineral profile in real ocean water doesn't break down under moisture the way concentrated sodium chloride coatings do. For high-humidity environments specifically, Grand Cayman tends to hold the longest on thick hair — dense strands absorb the mineral texture deeply enough that humidity has less to work against.
Can I use more than one formula?+
Yes, and some people with mixed hair types do. A common combination is using Hawaii at the roots for lift and 30A Seaside through the lengths for wave enhancement. There's no conflict between the formulas — the mineral profiles are complementary, not competing.
