Hair Thinning Treatment

Whole-Person Care That Looks for Why Your Hair Is Changing, for Women and Men
Personalized Hair Thinning Care at Lake Forest Regenesis
Provider-Guided Care That Starts With the Cause
Lake Forest Regenesis offers hair thinning treatment and evaluation for adults in Lake Forest, Chicago’s North Shore, and Lake County. Noticing more hair in the shower drain, a wider part, or a thinner ponytail can be unsettling, and it’s often hard to know where to start.
Thinning hair often has an underlying cause, like hormone changes, thyroid issues, nutritional deficiencies, stress, or medications. Products and supplements bought without knowing the cause can waste time and money. We look for the cause first, then talk through options that fit it.
We see both women and men, with care tailored to your pattern of hair loss and your goals. It’s part of our Hormone Optimization care, and it draws on our comprehensive lab testing.
Why Hair Thins
Your Hair Can Reflect What's Happening Inside
Hair growth depends on hormones, nutrition, thyroid function, stress levels, and overall health. Hair follicles are very active, so when something shifts in the body, hair is often one of the first places it shows.
Some shedding is normal. According to MedlinePlus, people lose up to about 100 scalp hairs a day, and most grow back. Thinning becomes a concern when shedding increases, regrowth slows, or the overall density of your hair changes.
Timing can be a clue. Significant stress, illness, surgery, childbirth, or rapid weight loss can trigger increased shedding a few months later. Hormonal and hereditary thinning, on the other hand, tends to develop gradually. Our article on hormonal and medical causes of hair thinning explains the most common reasons.
The Pattern Tells Us Where to Look
Thinning, Texture, Patches, or Pattern Loss
How hair is changing offers important clues. Is it general thinning, a change in texture, loss in patches or clumps, or a male-pattern shape such as a receding hairline or thinning crown?
Diffuse thinning across the scalp often points toward hormonal, thyroid, nutritional, or stress-related causes. Patchy loss can suggest an autoimmune or scalp condition that may need a dermatologist. Pattern thinning in men and women is often hereditary and hormone-related. Texture changes, like hair becoming finer or more brittle, can point toward thyroid or nutritional factors.
Each pattern points toward different possible causes and treatments, which is why we look closely before recommending anything. Photos taken over a few months can also help show whether things are changing.
Common Concerns We Evaluate
Thinning, Texture, Patches, Pattern Loss, Hormones & Stress
General Thinning
Less volume, a wider part, or a thinner ponytail that develops over time.
Texture Changes
Hair that feels finer, drier, coarser, or more brittle than it used to.
Patches or Clumps
Hair coming out in specific areas or in larger amounts than usual.
Pattern Hair Loss
A receding hairline or thinning crown, in men or women.
Hormone Changes
Shifts in thyroid, testosterone, or estrogen that can affect hair growth.
Stress & Medications
Both can trigger or worsen shedding, sometimes months after the cause.
A Personalized Approach to Hair Thinning
Care Built Around Your Cause and Your Goals
Allana looks at your labs, history, what you’ve already tried, and the pattern of your hair loss. Many people have already tried shampoos, supplements, or over-the-counter products by the time they come in, and knowing what did or didn’t help is useful.
She explains what your body is telling you and what your options are, including the risks, benefits, and realistic timelines of each. You decide what fits.
Hair grows slowly, so patience is part of any plan. We set expectations clearly and track progress over months, not days.
If your hair loss turns out to be temporary shedding after a stressful event, the best plan may simply be correcting any deficiencies and giving your hair time to recover. If it’s hereditary or hormonal, longer-term treatment may make more sense. Either way, you’ll understand why.
What to Expect at Your First Visit
Labs, History, and a Close Look at the Pattern
Your first visit covers your symptoms, medical history, medications, stress, diet, and past treatments, along with when you first noticed changes and whether hair loss runs in your family.
We order a comprehensive morning lab panel to check for nutritional deficiencies, thyroid issues, and hormone imbalances. Low iron stores are a common, often overlooked factor; our guide to ferritin and iron explains why iron stores are worth checking even when other results look normal. We also look at vitamin D and B12.
We’ll also take a close look at the pattern of your hair loss to help guide where to look next.
It helps to bring a list of any products, supplements, or medications you’ve used for your hair, and roughly how long you used them, so we can build on what you’ve already tried.
Hair Thinning Treatment Options
Guided by What We Find
Options depend on the cause, and many people combine approaches. Correcting an underlying issue, like a deficiency or thyroid problem, can be the most important step, with other treatments added to support regrowth.
Every option has potential benefits and risks. Some medications aren’t appropriate during pregnancy or with certain health conditions, so Allana reviews your history carefully before recommending anything.
Because hair grows in cycles, it often takes several months to see whether a treatment is helping, and stopping some treatments can reverse their benefits. We talk through all of this up front.
Topical Treatments
Applied directly to the scalp, when appropriate. Topicals usually need consistent daily use for several months before results can be judged.
Oral Medications
Prescription options, when they fit your cause and health. Some aren't appropriate during pregnancy or with certain conditions, so we review your history carefully first.
Hormone Support
When labs show a hormonal factor, such as thyroid or sex hormone changes, addressing it may support hair along with other symptoms. Learn about hormone optimization.
Nutritional Supplements & Peptides
Correcting deficiencies like low iron or vitamin D, and peptide therapy when appropriate, with clear expectations, since evidence for peptides in hair loss is still limited. Supplements are recommended based on your labs, since more isn't always better. Biotin, common in hair supplements, can affect some lab results, so let us know before your draw.
Hormones, Thyroid & Hair
Why Labs Come First
Thyroid changes, shifts in testosterone and estrogen, and perimenopause or menopause can all affect hair. In women, falling estrogen during the menopause transition can make hair finer. In men, sensitivity to certain hormones drives pattern thinning.
An underactive thyroid can cause diffuse thinning and coarser, drier hair, and it’s easy to miss without testing. Our thyroid panel guide explains what we look at.
That’s why labs are part of every evaluation. Learn about our thyroid care and perimenopause treatment.
Hair changes after childbirth are also common and usually temporary, as hormone levels settle. If shedding continues well beyond the postpartum months, it’s worth checking iron, thyroid, and other factors.
Thinning that comes with irregular periods, new acne, or new facial hair is worth evaluating for hormonal causes.
Nutrition, Stress & Hair
The Everyday Factors That Add Up
Low iron, vitamin deficiencies, ongoing stress, restrictive dieting, and some medications can all contribute to thinning. Hair is not essential for survival, so when the body is short on resources, hair growth is often one of the first things to slow.
Rapid weight loss, including during GLP-1 treatment, can also trigger temporary shedding. Getting enough protein and key nutrients during weight loss helps protect both muscle and hair.
Addressing these everyday factors can be an important part of your plan, and sometimes it’s the main fix.
Hair styling habits can matter too. Tight hairstyles, frequent heat styling, and harsh chemical treatments can cause breakage or traction-related thinning, so we may talk through simple changes that reduce stress on the hair while other treatments do their work.
When We Refer to a Dermatologist
For more invasive treatments like PRP injections, or more complex cases such as patchy, scarring, or rapidly progressing hair loss, Allana refers to a dermatologist and helps coordinate next steps.
