Hairdaze
Know your hair will look good on the day that matters.
Hairdaze is an iPhone app for tracking your hair-care routine. It records what you actually do — the wash, the products, the heat, the gym, your cycle, the weather — and learns how each one shows up in your hair. Then it forecasts your good hair days and tells you what to do before the ones you care about.
The bit everyone guesses at
You already know your hair has good days. You just can’t tell when the next one is.
Hairdaze started with a question my sister could never answer: when did I last wash this? Then: when was the last cut? Was it the new conditioner, or the humidity, or three days at the gym in a row? Most people keep this in their head, badly — and then hope for the best on the morning of something that matters.
- “Was that four days ago, or six?”
- “It was perfect last Thursday and I have no idea why.”
- “There are photos on Saturday. Do I wash it Friday or not?”
Hairdaze turns that guesswork into a record — and then does something useful with it.
How it works
Three steps. Most of them take ten seconds.
-
01
Log the day
What you washed with, what you put on it, what you did to it — and how it looked and felt to you, in one quick rating. Weather fills itself in. Cycle, workouts and heat styling are a tap each.
-
02
It learns your patterns
Within a couple of weeks Hairdaze starts connecting your inputs to your own ratings: which products your hair actually likes, how long your good stretch runs after a wash, what heat and humidity really cost you.

03
Plan around a date
Add the day you care about — a wedding, a shoot, a first date — and you get a forecast for it, plus the short list of things to do between now and then to land a good hair day on it.
What makes it different
Not a product catalogue. A forecast built from your own data.
Plenty of apps will tell you what a stranger’s hair liked. Hairdaze only cares about the patterns in your log — the things you control on one side, your own rating of how your hair looked and felt on the other. The insights engine turns that into a plain-language read on the week ahead and a few things worth changing.
- Built around events: pick the day that matters, then work backwards from it.
- Explains itself in sentences, not charts you have to decode.
- Sharpens the longer you log, and adjusts when your routine changes.
- Personal by design — your history, not an average of everyone else’s.
Hairdaze is built for confidence and planning, not diagnosis. It doesn’t offer medical advice — for anything to do with your scalp or your health, speak to a professional.
What you track
The things that actually move the needle.
Every one of these is an input the engine can weigh against how you rated your hair that day.
- Washes & conditioning
- Products used
- Heat styling
- Hairstyle worn
- Workouts & sweat
- Menstrual cycle
- Weather & humidity
- Salon appointments
- How it looked & felt
