What’s Actually Happening
Hair growth is directly influenced by your hormonal environment.
Each strand moves through a cycle: growth, transition, and shedding. When hormones shift, that cycle can get disrupted, usually meaning more shedding and less time spent growing.
A few key players:
- Estrogen, which helps keep hair in the growth phase longer
- DHT, a hormone that can shrink hair follicles over time. It is one of the most well-studied hormones linked to hormonal hair loss, known to gradually miniaturize follicles
- Progesterone, which helps keep things balanced
When estrogen declines or DHT becomes more active, you may notice more shedding, less density, or hair that feels finer overall.
Most people think of hair changes as cosmetic. In reality, they are often one of the first visible signs of internal hormonal shifts.
How This Shows Up Over Time
Hormonal hair changes do not happen all at once, and they do not look the same for everyone.
Pregnancy
Higher estrogen levels can make hair feel thicker, fuller, and easier to manage. For many women, this is when their hair feels its best.
Postpartum
A few months after giving birth, hormone levels shift quickly, and shedding often follows.
This is often referred to as postpartum hair loss, and it can feel sudden if you are not expecting it.
Perimenopause
This is where things tend to feel the most confusing.
Hormones fluctuate, not just decline, so the changes can feel inconsistent.
One of the biggest misconceptions is that hair thinning only starts during menopause. In reality, it often begins earlier, during perimenopause, when hormone levels are fluctuating the most.
Perimenopause hair loss is one of the most common, yet least discussed, symptoms of this stage.
You might notice:
- Thinning around the temples
- Less volume when you style your hair
- A ponytail that feels smaller
- Hair that does not behave the way it used to
For a lot of women, this is the ‘what is happening?’ phase.
Menopause
As hormone levels stabilize at a lower level, changes in hair tend to become more consistent, usually slower growth and less density over time.
