Shea › 4C hair growth app
the 4C hair growth app: tracking length through shrinkage
Short answer: Shea (free on iPhone and Android). It logs stretched length and progress photos over months, so shrinkage stops hiding what your hair is actually doing. It also plans the wash day and tracks the products behind the result, because on 4C hair the number that moves is usually retention rather than growth.
Almost everyone who says their 4C hair "is not growing" is wrong about the cause. Hair grows at roughly half an inch a month for most people, and coily hair is no different. What is different is how much of that length stays on your head, and how completely shrinkage hides the part that does.
growth and retention are not the same thing
Your scalp produces new hair at a fairly steady rate. You cannot do much to speed that up, and any product promising otherwise is selling you something. What you can change is how much of it survives.
Coily hair is more fragile where the strand bends, and the oldest, driest part is the ends. If you grow half an inch and break off half an inch, your hair sits at exactly the same length for a year while growing six inches. That is the position most people are in when they get frustrated, and it is a retention problem, not a growth problem. The fix is gentler handling, more moisture, protective styling and consistency, not a stronger growth oil.
why shrinkage makes this so hard to see
4C hair can shrink to a fraction of its stretched length. Shrinkage also changes with humidity, with the product you used, and with how the style was set, which means the hair in your mirror looks like a different length on two consecutive days without a single strand changing.
That is why memory is useless here. You cannot recall in March how long your hair felt in November with enough precision to tell four months of growth from none, and the day-to-day noise is bigger than the monthly signal. A written record is the only thing that resolves it.
how to measure 4C hair properly
Measuring is simple, but it only works if you keep it identical each time:
Pick one section, usually the crown or the nape, stretch it the same way, and measure to the same point. Do it once a month rather than once a week: hair does not move fast enough for weekly numbers to mean anything, and checking too often is how people talk themselves into thinking nothing is happening.
four months in and it's working 🫶🏾
the part a tracker alone cannot do
A chart tells you what happened. It does not tell you why, and it does not tell you whether what you are seeing is normal.
That is what the Circle is for: 4,000+ Black women with 4C, 4B, 4A, 3C, 3B and 3A hair, in the app, every day. Post your four-month photos and someone with the same texture will tell you whether your ends look thin, whether that is a protein problem, and what they did about it. It is the difference between a number and an answer.
what Shea tracks
a realistic timeline
At around half an inch a month, six months of good retention is about three inches. On stretched 4C hair that is visible. On shrunken 4C hair it can be almost invisible, which is exactly why the log matters more than the mirror. Give any routine three months before you judge it, and change one thing at a time so you can tell what did the work.
is Shea free?
Yes. Shea is free on iPhone and Android. Length logging, progress photos, wash day planning and the Circle are on the free tier. Premium raises some limits and is optional. Progress photos are blurred on your phone before anything uploads, with a toggle if you would rather keep your face, and nothing is sold on.
