Because healthy-looking hair starts with understanding what’s happening at the root.
Noticing more hair in your brush, a widening part, or a thinner ponytail can be unsettling. Hair thinning affects both women and men, and it can happen for many reasons, including hormonal changes, genetics, stress, nutritional deficiencies, and significant weight loss.
If you’re searching for hair loss treatment in Pasadena, understanding what’s causing your hair to thin is the first step toward finding an appropriate solution.
At Infinite Wellness Med Spa in Pasadena, California, we offer personalized consultations and non-surgical hair restoration options, including:
- Fotona HairRestart – Noninvasive laser-based scalp treatment.
- PRF Hair Restoration – Platelet-rich fibrin treatments using components from your own blood.
- REVIAN RED Hair Growth Cap – At-home red light therapy for certain types of pattern hair loss.
In this guide, we’ll explain why hair loss happens, when to seek professional evaluation, and what to know about available hair restoration treatments.
Understanding Hair Loss: How Hair Growth Works
Hair grows in a natural cycle consisting of several phases:
- Anagen (Growth Phase): Hair follicles actively produce new hair.
- Catagen (Transition Phase): Hair growth slows as follicles transition toward rest.
- Telogen (Resting Phase): Hair follicles remain relatively inactive.
- Exogen (Shedding Phase): Older hairs shed as part of the natural cycle.
It’s normal to shed approximately 50–100 hairs per day, although individual shedding patterns vary.
Hair thinning becomes more noticeable when excessive shedding occurs, fewer follicles produce new hair, or existing strands become progressively finer.
Common Signs of Hair Thinning
You may notice:
- A widening part or more visible scalp
- Thinning around the temples or hairline
- Reduced overall hair volume
- A thinner ponytail
- Increased shedding during washing or brushing
- Gradual loss of hair density
These changes can result from different conditions. Identifying the cause is essential because not all types of hair loss respond to the same treatment.
What Causes Hair Loss in Women and Men?
Hair loss has many possible causes. Some are temporary, while others may be progressive and require ongoing management.
- Hormonal Changes and Hair Thinning
Hormonal fluctuations can affect the normal hair-growth cycle.
Common contributing factors include:
- Pregnancy and postpartum hormonal changes
- Perimenopause and menopause
- Thyroid disorders
- Androgen-related conditions
For women, hormonal transitions may coincide with gradual thinning along the part or crown.
An evaluation can help determine whether hormonal factors may be contributing to hair loss.
- Stress, Illness, and Surgery
Significant emotional or physical stress can trigger a temporary form of shedding known as telogen effluvium.
Common triggers include major illness, high fever, surgery, significant emotional stress, and other physical stressors.
Shedding often becomes noticeable two to three months after the triggering event.
In many cases, hair gradually recovers after the underlying stressor resolves, although recovery timelines vary.
- Nutritional Deficiencies
Healthy hair growth depends on adequate nutrition.
Insufficient protein intake or certain nutritional deficiencies may contribute to hair thinning.
Potential factors include:
- Low iron levels
- Inadequate protein intake
- Zinc deficiency
- Certain vitamin deficiencies
Taking supplements without identifying a deficiency is not always beneficial and may sometimes be harmful.
A healthcare professional may recommend testing when nutritional deficiencies are suspected.
- Genetics and Pattern Hair Loss
Androgenetic alopecia, commonly called male-pattern or female-pattern hair loss, is one of the most common causes of progressive hair thinning.
It can cause hair follicles to gradually produce finer, shorter strands.
Men may notice thinning around the temples or crown, while women frequently experience widening of the central part or diffuse thinning across the top of the scalp.
Because genetic hair loss can progress over time, earlier evaluation may provide more treatment options.
- Hair Loss After Rapid Weight Loss or GLP-1 Medications
Rapid or significant weight loss can sometimes lead to temporary hair shedding.
This may be associated with changes in calorie intake, inadequate protein consumption, nutritional deficiencies, or physical stress related to weight loss.
Some individuals taking GLP-1 medications for weight management also report increased shedding.
However, hair loss during GLP-1 treatment is not necessarily caused directly by the medication. Weight changes, nutritional factors, and other medical conditions may contribute.
If you experience significant shedding during weight loss, discuss your symptoms with a qualified healthcare professional.
- Other Medical and Scalp Conditions
Additional causes of hair loss include alopecia areata, inflammatory scalp conditions, infections, certain medications, and traction from tight hairstyles.
Some conditions can permanently damage hair follicles.
Sudden, patchy, painful, or inflammatory hair loss should be evaluated promptly by a qualified medical professional.
When Should You Seek Hair Loss Treatment?
If you’re experiencing persistent or worsening hair thinning, professional evaluation can help identify possible causes and determine which treatments may be appropriate.
You should seek medical evaluation promptly if you experience:
- Sudden or patchy hair loss
- Rapid or unexplained shedding
- Scalp redness, pain, or swelling
- Persistent itching, scaling, or sores
- Shiny or scarred areas of scalp
- Loss of eyebrow or eyelash hair
Some of these symptoms may indicate a condition requiring medical or dermatologic treatment rather than cosmetic hair restoration.
Non-Surgical Hair Restoration Options in Pasadena
Not everyone experiencing hair loss needs surgery.
Depending on the underlying cause, non-surgical hair restoration treatments may be considered as part of a broader plan that can include medical treatments, nutritional guidance, or other interventions.
At Infinite Wellness Med Spa, we offer several hair restoration options for appropriate candidates.
Fotona HairRestart: Laser Hair Restoration
Fotona HairRestart is a noninvasive, laser-based treatment designed to deliver controlled energy to the scalp.
It uses Fotona Er:YAG laser technology to provide controlled scalp heating through a nonablative treatment approach.
The proposed goal is to influence the tissue environment around hair follicles and potentially support healthier hair growth.
Potential Advantages of Fotona HairRestart
- Non-surgical treatment
- No injections required
- No incisions
- Designed for scalp treatment
- May be considered as part of a broader hair restoration plan
Early clinical studies of nonablative Er:YAG laser treatment have reported encouraging results in some patients with androgenetic alopecia. However, evidence remains limited, and the effectiveness of a specific protocol cannot be assumed from studies of other light-based devices. PubMed Central (PMC)
Results vary based on individual circumstances and the underlying cause of hair loss.

PRF Hair Restoration: A Platelet-Based Treatment
Platelet-rich fibrin (PRF) is prepared using a small sample of a patient’s own blood.
The preparation process produces a platelet-containing fibrin material that may include signaling proteins involved in tissue repair.
When injected into selected areas of the scalp, PRF is intended to support the local tissue environment surrounding hair follicles.
What Makes PRF Hair Restoration Different?
PRF is a procedure-based treatment that uses components derived from your own blood.
Potential characteristics include:
- Uses an autologous blood preparation
- Does not require surgery
- Can target selected scalp areas
- May be considered for certain hair-thinning patterns
Research on PRF specifically for hair restoration is still developing.
There is a larger, although also evolving, body of evidence for platelet-rich plasma (PRP). PRP and PRF are different preparations, and results from PRP studies should not automatically be attributed to PRF.
Your provider can discuss the available evidence, limitations, and whether treatment is appropriate for your needs.

REVIAN RED Hair Growth Cap: At-Home Red Light Therapy
The REVIAN RED Hair Growth Cap is a wearable light-therapy device designed for certain adults experiencing pattern hair loss.
Unlike in-office procedures, this treatment can be used at home according to the manufacturer’s instructions.
The device uses red LED light, including wavelengths identified by its manufacturer as 620 nm and 660 nm.
It is FDA-cleared for a specific hair-growth indication. FDA clearance does not mean that every person will experience hair regrowth or that the device is appropriate for every type of hair loss.
How Does the REVIAN RED Cap Work?
The manufacturer’s recommended routine is approximately 10 minutes per day.
The treatment is intended to deliver light energy to the scalp, with the goal of supporting hair growth in appropriate candidates.
Potential benefits of the treatment approach include:
- At-home convenience
- Noninvasive application
- Short daily treatment sessions
- No needles or surgery
Consistency is important, and several months of use may be necessary before results can be evaluated.
Not everyone will experience noticeable improvements.
Individuals with photosensitive conditions, those taking photosensitizing medications, or those experiencing unexplained scalp symptoms should consult a healthcare professional before use.
The REVIAN RED Hair Growth Cap is available for purchase at Infinite Wellness Med Spa in Pasadena. Ask our team whether it may be suitable for your needs.
How Long Does Hair Restoration Take?
Hair restoration is generally a gradual process.
Because hair follicles follow natural growth cycles, improvements may take several months to become noticeable when treatment is effective.
Your expected timeline depends on several factors, including:
- The underlying cause of your hair loss
- How long thinning has been occurring
- The health and condition of your hair follicles
- Your selected treatment
- Individual response to treatment
Some treatments require continued use to maintain improvements.
During your consultation, your provider can explain realistic expectations based on your individual circumstances.
How to Support Healthier Hair Between Treatments
Professional hair restoration treatments may be helpful for some people, but everyday habits also play an important role in overall hair and scalp health.
Consider these practices:
Prioritize adequate nutrition. Eat a balanced diet with sufficient protein and address confirmed nutritional deficiencies with medical guidance.
Avoid excessive tension on the hair. Tight hairstyles may contribute to traction-related hair loss.
Limit unnecessary heat and chemical damage. Gentle hair-care practices may help reduce breakage.
Manage stress and prioritize sleep. Maintaining general health supports normal body functions, including the hair-growth cycle.
Address scalp concerns. Persistent inflammation, irritation, or other symptoms should be evaluated by a healthcare professional.
Review medications when appropriate. If hair shedding begins after a medication change, consult your prescribing clinician before changing treatment.
These practices support general hair and scalp health but cannot prevent or reverse every form of hair loss.
Frequently Asked Questions About Hair Loss Treatment
What is the best hair loss treatment in Pasadena?
The most appropriate treatment depends on the cause of hair loss.
Some conditions may benefit from established medical therapies, while selected patients may consider procedural or device-based options such as Fotona HairRestart, PRF, or red light therapy.
A professional evaluation is the best starting point.
Can thinning hair grow back?
In some cases, yes.
Temporary shedding associated with illness, stress, or nutritional factors may improve when the underlying issue is addressed.
Other types of hair loss may require ongoing management, while scarring conditions can permanently damage hair follicles.
Does Fotona HairRestart work for hair thinning?
Preliminary clinical research involving nonablative Er:YAG laser treatments suggests potential benefits for some individuals with pattern hair loss.
However, results vary, and additional research is needed to establish the effectiveness of specific treatment protocols.
Is PRF hair restoration the same as PRP?
No.
PRF and PRP are both platelet-based preparations derived from a patient’s blood, but their preparation methods and composition differ.
Research supporting PRF specifically for hair restoration remains limited compared with PRP.
Can GLP-1 medications cause hair loss?
Hair shedding has been reported during weight loss associated with GLP-1 medications.
However, rapid weight changes, inadequate nutrition, and other health factors may contribute.
A healthcare professional can help evaluate persistent or concerning shedding.
Are non-surgical hair restoration treatments painful?
The experience varies by procedure.
Fotona HairRestart is noninvasive, whereas PRF involves injections. At-home red light therapy does not require injections.
Your provider can explain what to expect with each option.
