Most people have no idea if their hair is actually growing. They just guess — and then panic when it seems stuck at the same length for months. The truth? Hair grows about half an inch per month for most people. You just can't see it without tracking it properly.
This guide gives you the exact method to measure and track hair growth at home — and how to use the free HairCareTracker app to make it automatic.
Why Tracking Hair Growth Matters
When you don't track, you can't tell if your routine is working. You try a new oil, feel like nothing happened, and give up — even though your hair might have grown an inch that month. Tracking gives you real data so you can double down on what works and drop what doesn't.
📏 Hair grows an average of 6 inches per year — about 0.5 inches per month. Tracking lets you see if you're above or below that, and why.
The Right Way to Measure Hair Growth
What You Need
- A soft measuring tape (or a string + ruler)
- A mirror or a friend to help
- A consistent reference point on your head
Step 1 — Pick Your Reference Points
Measure from the same spot every single time. Best spots are the crown, the nape of the neck, and the sides above your ears. Mark these spots in your hair journal so you never forget.
Step 2 — Measure in a Straight Line
Don't stretch the hair — let it fall naturally. Measure from root to tip in a straight line. If your hair is curly, measure it stretched (not pulled tight, just extended) for consistency.
Step 3 — Log It Immediately
Write it down or log it in your hair tracker app the moment you measure. Don't rely on memory.
Step 4 — Take a Progress Photo
Same wall. Same lighting. Same angle (front and back). This is your visual proof. A photo tells the story measurements can't — density, health, thickness.
Step 5 — Compare Monthly
Do this on the same day every month — first of the month works great. After 3 months, you'll have enough data to see real trends.
How to Track Hair Growth With an App
The HairCareTracker app (Jordyn Hair Journal) has a built-in growth tracker where you log your hair length each month and compare progress photos side by side. You can also log what products and routines you're using, so you'll know exactly what caused your growth spurt (or slowdown).
- Log monthly length measurements
- Compare progress photos in a gallery
- See your growth history over time
- Connect growth data to your wash day logs and products
What to Do If Your Hair Isn't Growing
If your measurements stay flat for 2+ months, look at these common causes:
- Breakage: Hair is growing but breaking at the same rate. Check moisture/protein balance.
- Tight styles: Edges and nape often break from tight ponytails or braids.
- Skipping protective styles: Ends break when exposed to friction constantly.
- Not deep conditioning: Dry hair breaks. More moisture = less breakage = more visible length.
Your hair journal data will show you which of these is the culprit — because you'll be able to see exactly what changed in the months your hair stopped growing.

How often should I measure hair growth?
Once a month is ideal. More frequent measurements can be discouraging because the changes are too small to see week to week. Monthly gives you enough time to see real progress.
What's the best hair growth tracker app?
HairCareTracker (Jordyn Hair Journal) is one of the best free hair growth tracker apps — it combines length logging, progress photos, wash day logs, and AI guidance in one app.
How much should hair grow in a month?
On average, hair grows about 0.5 inches (1.25 cm) per month, or 6 inches per year. This varies by genetics, health, and hair care practices. Tracking helps you see your personal baseline.
