Low testosterone, or hypogonadism, can sometimes cause hair loss. The medical term for this type of hair loss is androgenic alopecia. Testosterone gets converted into a hormone called dihydrotestosterone (DHT), which can shrink hair follicles on the scalp. As the follicles get smaller, the hair weakens and falls out more easily.
However, for many men, hair loss is reversible with treatment that raises testosterone levels back to normal. Getting testosterone levels checked and addressing any deficiency is an important first step. Treatments may include:
- Testosterone replacement therapy - This involves getting testosterone directly through gels, patches, injections or pellets implanted under the skin. It's crucial to get the dosage right under a doctor's supervision. Too much testosterone can actually speed up hair loss.
- Medications - Drugs like clomiphene citrate or human chorionic gonadotropin (hCG) can help the body produce more of its own testosterone.
- Lifestyle changes - Improvements in diet, exercise, sleep and stress management can give a boost to flagging testosterone.
If low testosterone is caught early and properly treated,
significant hair regrowth is possible. However, results vary from person to person. Here's an overview of what to expect:
Regrowth timeline
- Initial shedding - About 2-4 months into treatment, more hair shedding may occur. This is a sign that thinner hairs are falling out to make room for new growth.
- Early regrowth - After 4-8 months, tiny hairs may visibly start sprouting in bald or thinning areas.
- Significant regrowth - Within 9-15 months, regeneration of 30-50% of lost hair may occur if testosterone treatment is consistent.
- Peak regrowth - It can take up to 2 years to achieve maximum, visible hair growth from testosterone restoration. Consistency is key.
Other factors influencing hair regrowth
- Genetics - Those with a strong family history of extensive male pattern baldness tend to have lower regrowth potential.
- Age - Younger males in their 20s and 30s have better hair follicle regeneration ability compared to those over 50.
- Speed of treatment - Getting tested and treated very quickly after onset of hair loss leads to superior regrowth capability.
- Scalp health - Good blood circulation and a healthy scalp environment helps restored follicles thrive. Massage, microneedling and laser therapy can assist.
Maintaining regrowth
- After hormone levels get balanced and hair regrows, it's essential to continue testosterone therapy and healthy lifestyle habits. Otherwise, DHT may again accumulate and shrink restored follicles. Consult an endocrinologist to tailor a treatment plan for the long term.
In summary, robust hair regrowth from testosterone deficiency is often achievable through prompt diagnosis and properly monitored treatment. Be patient, as the process spans months. See an endocrinologist specializing in hormones and hair loss for best restoration success.
