Comparison
StrandVoice vs Compar
Both are AI hair apps for textured, curly, and color-treated hair. Compar is a free selfie scan that matches you to products to buy. StrandVoice is a paid assistant that starts with the products already on your shelf and builds a routine you can actually keep.
| StrandVoice | Compar | |
|---|---|---|
| Main job | Build and keep a real routine around your hair, your schedule, and your products | Match a selfie scan to products you could buy |
| Products you already own | Shelf you fill in; Zara audits it for conflicts, duplicates and heroes | Not the focus — recommendations point at new purchases |
| Memory | Remembers your hair length, porosity, past reactions, and what you told her last month | Scan-by-scan; little continuity between sessions |
| Routine and reminders | Calendar with wash day, protein vs moisture spacing, sleep protection, and reminders | No routine calendar |
| Your stylist | Stylist Brief you can read aloud or text your stylist between appointments | No stylist hand-off |
| Price | $9/month, 7 days free, no card to start | Free, monetised through product recommendations |
A scan is a snapshot. A routine is a habit.
A scan tells you what your hair looks like today. It doesn't know you skipped wash day twice because work was brutal, that you're swimming Saturday, or that the clarifying shampoo under your sink is what's stripping your color. Zara tracks all of that and adjusts the plan — protein and moisture spaced properly, chelating wash the day after the pool, sleep protection every night.
Who Compar is better for
If you want a free, one-off product suggestion and you're happy to figure out the routine yourself, a free scanner does the job. StrandVoice earns its $9 when you want someone in your corner between salon visits.
