Clients often ask why their hair suddenly seems thicker, darker, or faster-growing. The answer isn't usually their waxing routine, it's often their hormones.
From puberty and pregnancy to menopause and conditions like PCOS, hormonal changes can dramatically affect where hair grows, how quickly it returns, and its texture.
Understanding these changes helps estheticians set realistic expectations, create personalized treatment plans, and recognize when a client may benefit from medical evaluation.
How hormones influence hair growth
Every hair follows a natural growth cycle with three phases:
- Anagen: the active growth phase.
- Catagen: the transition phase.
- Telogen: the resting and shedding phase.
Hormones influence both the length of these phases and the activity of the hair follicle itself.
That's why two clients receiving the exact same waxing service can experience completely different regrowth patterns.
Because hair grows in cycles, clients often notice changes in regrowth after several waxing appointments. Understanding the hair growth cycle also helps explain why regular waxing may lead to finer, slower regrowth over time. Learn more in our article Does Waxing Make Hair Grow Back Thinner?
The role of androgens
The hormones that have the greatest influence on hair growth are androgens.
Although often referred to as "male hormones," women naturally produce androgens as well through the ovaries and adrenal glands.
Hair follicles contain androgen receptors. When stimulated, they can lead to:
- Faster hair growth
- Thicker, coarser hair
- Darker pigmentation
- Conversion of fine vellus hair into terminal hair
Areas most sensitive to hormonal changes include:
- Chin
- Upper lip
- Jawline
- Neck
- Chest
- Abdomen
- Lower back
Genetics also play an important role, which explains why clients respond differently to similar hormonal changes.
Puberty: when hair growth changes begin
For many clients, puberty marks the beginning of noticeable body hair growth.
As androgen levels increase, terminal hair develops on the:
- Underarms
- Bikini area
- Legs
- Face (particularly in males)
For many women, this is also when facial waxing becomes part of their regular beauty routine.
Pregnancy: temporary changes
Pregnancy can temporarily change hair growth patterns.
Higher estrogen levels often keep hair in the anagen phase longer, making scalp hair appear fuller and thicker. Some clients also notice increased facial or body hair during pregnancy.
After childbirth, hormone levels shift quickly. Hair that remained in the growth phase enters the shedding phase together, leading to temporary postpartum hair loss.
Clients may also notice temporary changes in body hair growth before things gradually return to normal.
Menopause and facial hair
One of the most common questions mature clients ask is:
"Why am I suddenly growing chin hair?"
During menopause, estrogen levels decrease while androgen levels decline more gradually. This hormonal shift can make androgen-related hair growth more noticeable.
Clients may experience:
- Increased chin hair
- Upper lip hair
- Coarser facial hair
- Faster facial regrowth
- Thinning eyebrows
At the same time, scalp hair often becomes finer.
Reassurance and education are just as important as the waxing service itself.
PCOS and excessive hair growth
Polycystic ovary syndrome (PCOS) is one of the most common hormonal conditions affecting hair growth.
Clients with PCOS may experience:
- Excess facial hair (hirsutism)
- Chest or abdominal hair
- Thick, coarse regrowth
- Acne
- Oily skin
- Irregular menstrual cycles
Waxing effectively removes unwanted hair but does not treat the underlying hormonal imbalance.
If a client reports sudden excessive facial hair growth along with other symptoms, encourage them to consult a qualified healthcare provider.
Thyroid disorders
The thyroid also influences the hair growth cycle.
Both hypothyroidism and hyperthyroidism may contribute to:
- Hair thinning
- Increased shedding
- Changes in hair texture
- Slower regrowth
These conditions typically affect scalp hair more than body hair but can influence overall hair density.
Medications can affect hair growth
Certain medications may also change hair growth patterns, including:
- Hormonal contraceptives
- Hormone replacement therapy
- Testosterone therapy
- Fertility medications
- Some corticosteroids
A thorough consultation can often explain unexpected changes in waxing results.
Set realistic expectations
Clients experiencing hormonal hair growth are often searching for a permanent solution.
It's important to explain that professional waxing:
- Removes hair from the follicle
- May lead to softer regrowth over time
- Can weaken individual follicles after years of consistent waxing
However, waxing cannot stop hormones from stimulating new hair growth.
New follicles may continue to become active, even in long-term waxing clients.
Setting realistic expectations protects both the client and your professional credibility.
Helping clients understand how hormones affect hair growth is just as important as educating them about the waxing process itself. Setting realistic expectations builds trust and encourages clients to stay consistent with their treatment schedule.

The consultation matters
When a client reports significant changes in hair growth, ask thoughtful questions such as:
- When did you first notice the change?
- Has the hair become darker or coarser?
- Are you taking any new medications?
- Have you recently been pregnant?
- Have your menstrual cycles changed?
- Have you ever been diagnosed with a hormonal condition?
Your role is not to diagnose.
Your role is to recognize patterns, provide safe and effective waxing services, and recommend medical evaluation when appropriate.
Supporting clients through hormonal changes
Hormonal hair growth can have a significant emotional impact.
Many clients feel embarrassed, frustrated, or discouraged by changes they cannot control.
Providing a judgment-free environment, educating clients about realistic expectations, and maintaining a consistent waxing schedule can make a meaningful difference in their confidence.
Knowledge is one of the most valuable tools an esthetician can offer.
Understanding the relationship between hormones and hair growth helps you deliver better consultations, personalize treatment plans, and strengthen long-term client relationships.
Frequently asked questions
Can hormones make hair grow back thicker?
Hormones can stimulate thicker or darker hair growth in certain areas, particularly the face and body. Waxing does not cause this change.
Does waxing help hormonal hair growth?
Waxing effectively removes unwanted hair and may weaken individual follicles over time, but it does not treat the hormonal cause of excess hair growth.
Why do women develop chin hair during menopause?
As estrogen levels decline, androgen activity becomes more noticeable, which can lead to increased facial hair growth.
Can PCOS cause excessive facial hair?
Yes. PCOS is one of the most common causes of hirsutism, or excessive facial and body hair growth in women.
Should estheticians diagnose hormonal disorders?
No. Estheticians should recognize unusual hair growth patterns, educate clients, and recommend consultation with a qualified healthcare provider when appropriate.
