"I've Been Taking Minoxidil for Over a Year, So Why Is My Hair Still Falling Out?" A Houston Hair Loss Specialist Explains
Hair loss can be one of the most frustrating conditions to treat because improvement doesn't always mean the problem has stopped. Many women begin treatment with oral minoxidil, notice new hairs growing in, yet continue to see excessive shedding in the shower or while brushing their hair.
This exact concern brought a 43-year-old woman back to our hair loss clinic in Houston. Although she had been taking oral minoxidil for approximately 18 months and had already seen encouraging regrowth, she still felt like her hair simply "wouldn't stay on her head."
If you've been wondering whether your medication has stopped working—or whether you need additional treatment—you're not alone.
The Patient's Story
Our patient had experienced slowly progressive hair thinning for nearly eight years. Her hair loss was generalized throughout the scalp rather than occurring in isolated patches. Like many women with hereditary hair loss, she also had a family history of thinning hair in her father, making genetic hair loss a likely diagnosis.
For the previous year and a half, she had been taking low-dose oral minoxidil (half of a 2.5 mg tablet daily). While she noticed new hairs growing, she remained frustrated because the overall density of her hair continued to decline.
She asked one of the most common questions we hear:
"If my hair is growing back, why does it still keep falling out?"
Understanding Female Pattern Hair Loss
After performing a detailed scalp examination using dermoscopy, the findings were consistent with female pattern hair loss (androgenetic alopecia).
Unlike sudden shedding disorders, androgenetic alopecia is a chronic, genetically programmed condition. The hair follicles gradually shrink over time, producing progressively thinner hairs until they eventually stop producing visible hair altogether.
Women often notice:
A widening part
Decreased ponytail thickness
Diffuse thinning over the top of the scalp
Increased hair shedding during washing or brushing
Hair that grows back finer than before
Because this process develops slowly over many years, many women don't realize how much hair they've lost until significant thinning has already occurred.
Why Minoxidil Helps—but May Not Be Enough
Oral minoxidil is one of the most effective medications available for stimulating dormant hair follicles.
It works by:
Increasing blood flow to hair follicles
Extending the hair growth (anagen) phase
Encouraging thicker hair shafts
Improving overall hair density
However, minoxidil does not directly block the hormones responsible for follicle miniaturization.
That's why many women eventually benefit from combination therapy rather than relying on one medication alone.
Why We Increased Her Treatment
Because she had experienced partial improvement on a lower dose of oral minoxidil, we discussed optimizing her treatment plan.
Her updated regimen included:
Increasing oral minoxidil to 2.5 mg once daily
Starting spironolactone 50 mg twice daily
Spironolactone works differently than minoxidil.
Instead of stimulating growth, it helps reduce the effects of androgens (male-type hormones) on genetically sensitive hair follicles. For many women, combining these medications provides better long-term stabilization than either medication alone.
Because spironolactone can affect potassium levels, kidney function, and liver function, laboratory monitoring was ordered before and during treatment. Women taking spironolactone should also avoid pregnancy because the medication can cause birth defects.
Other Hair Restoration Options We Discussed
Every patient's treatment plan is individualized. During her visit, we also reviewed several additional therapies that can further improve hair density.
Platelet-Rich Plasma (PRP)
PRP hair restoration uses the patient's own platelets to deliver concentrated growth factors directly to weakened hair follicles. These natural proteins may improve follicle activity and promote thicker, healthier hair growth.
Many patients choose PRP alongside oral medications for enhanced results.
Alma TED Hair Restoration
Alma TED is an innovative, needle-free treatment that uses ultrasound technology and air pressure to deliver specialized hair growth serum deep into the scalp.
Patients often appreciate Alma TED because:
No injections are required
No downtime is needed
Treatments are comfortable
It can complement oral medications and PRP
Low-Level Laser Therapy
Medical-grade laser devices stimulate follicular metabolism and may help maintain existing hair while supporting new growth.
Nutritional Hair Supplements
Evidence-based supplements such as Nutrafol, Viviscal, and physician-recommended hair vitamins may provide additional support, particularly when nutritional deficiencies contribute to thinning.
Hair Loss Is a Marathon, Not a Sprint
One of the biggest misconceptions about hair restoration is expecting permanent improvement after starting one medication.
Female pattern hair loss is progressive, meaning treatment is focused on:
Slowing ongoing miniaturization
Preserving existing hairs
Stimulating new growth
Maximizing long-term hair density
Because hair grows slowly, meaningful improvement often requires 6–12 months, with continued treatment necessary to maintain results.
An Important Reminder About Genetics
Many women believe they cannot have hereditary hair loss because no women in their family experienced thinning.
In reality, the genes responsible for androgenetic alopecia can come from either side of the family, including your father.
Having a father with hair loss can significantly increase your own risk.
Why a Comprehensive Evaluation Matters
Not every patient with hair thinning has the same diagnosis.
At our Houston and Katy dermatology clinics, evaluation may include:
Dermoscopic scalp examination
Medical history review
Family history assessment
Laboratory testing when appropriate
Discussion of hormonal factors
Review of current medications
Development of a customized treatment plan
The earlier treatment begins, the greater the chance of preserving existing hair follicles before permanent miniaturization occurs.
