Not all hair loss can be prevented. Pattern hair loss is largely genetic. But many other causes of thinning and breakage can be reduced, and early attention to gradual thinning gives you more options. This guide separates what you can control from what you cannot.
What you cannot fully control
- Genetics. Pattern hair loss runs in families and depends on how sensitive your follicles are to androgens.
- Age. Hair naturally becomes finer with age for many people.
- Some medical conditions, such as autoimmune conditions like alopecia areata.
What you can influence
- Nutrition. Enough protein, iron and calories support normal hair growth. Crash diets and rapid weight loss can trigger shedding. See hair loss after weight loss.
- Underlying conditions. Getting thyroid problems or iron deficiency identified and treated. See iron deficiency hair loss.
- Styling habits. Tight ponytails, braids and extensions can cause traction alopecia. Heavy heat and chemical treatments cause breakage.
- Scalp health. Treating dandruff and scalp inflammation. See common scalp issues.
- Stress and sleep. Major stress can trigger shedding a few months later.
- Smoking. Smoking has been associated with hair loss, among its many other harms.
- Medications. If you suspect a medication is affecting your hair, talk to the prescriber rather than stopping it.
Acting early on pattern hair loss
Pattern hair loss is progressive. Treatments work best at slowing or stopping further loss, and follicles that have been inactive for a long time are less likely to respond. That is why many people choose to have a provider review gradual thinning early rather than waiting. Options may include minoxidil and, for some people, prescription medications. See treatments with the strongest evidence.
When to see a doctor
See a doctor for sudden or patchy hair loss, scalp pain or scarring, or hair loss with other symptoms such as fatigue or weight change.
