Suited to people with fine, thin, or limp hair who want root lift and body from a leave-in foam without a stiff or sticky finish. It's a retail styling product for home use — no professional application is required, though it's sold as a professional-grade formula through beauty supply channels.

It combines root-lift styling and a pH-balancing, vinegar-rinse-style shine boost in a single leave-in step, so fine or limp hair gets body and shine without needing a separate clarifying rinse.

Shake the can well and dispense with the can inverted. Apply an egg-sized amount into your palm and work it through damp or dry hair, focusing on the roots for lift. Comb through for even distribution, then air-dry or blow-dry as desired. It is a leave-in product and is not rinsed out.

Pros:

• Apple cider vinegar helps balance hair's pH for a smoother, shinier finish
• Leave-in foam adds root volume without a stiff or crunchy cast
• Includes a PABA-free UV filter and thermal protection for daily styling
• Lightweight, medium-hold formula suits fine or limp hair

Cons:

• Medium hold may not be enough for coarse hair or very humid conditions
• Brand has not published a full INCI ingredient list, so allergy-conscious buyers should patch test
• Being a leave-in, it needs to be styled/dried in rather than rinsed out like a treatment
