10 facts about hair loss the industry profits from you not knowing:
1.47% of male pattern hair loss patients are vitamin D deficient
2.The studied dose of saw palmetto is 320mg, most supplements won’t tell you their dose
3.Rosemary oil matched minoxidil 2% in a randomised controlled trial
4.Biotin supplementation has no evidence for hair growth in non-deficient people
5.Pumpkin seed oil produced a 40% increase in hair count in a double-blind RCT
6.Dutasteride’s half-life is 5 weeks, finasteride’s is 6 hours. They are not the same drug
7.Ferritin, not haemoglobin, is the correct iron test for hair loss
8.Cortisol can push 70% of growing hairs into the resting phase during chronic stress
9.Most postpartum hair loss resolves naturally
10.Your hair follicle is not dead. It is miniaturised. The window to act is still open.
7 things that happen to your hair follicle when DHT levels are too high:
1.DHT binds to androgen receptors in the dermal papilla cells
2.The dermal papilla shrinks and produces less of the growth signals the follicle needs
3.The anagen (growth) phase shortens with each successive hair cycle
4.The hair that grows back is progressively thinner, shorter, and finer
5.The telogen (resting) phase lengthens, so less time is spent growing
6.Over years the follicle miniaturises to the point of producing vellus (invisible) hair
7.The follicle is still alive at this stage, which is why early intervention with the right protocol works
The follicle is not dead. The window is still open. Act early.

5 reasons saw palmetto is the most underrated compound in hair loss science:
https://t.co/5j3y1BtLD6 works on the same 5-alpha reductase pathway as finasteride without destroying your hormones
2.A 2020 systematic review of 5 RCTs showed 83% of patients had increased hair density
3.The same review found a 27% increase in total hair count
4.A 2025 randomised controlled trial showed significant improvement in terminal hair count at 90 days
5.The studied dose is 320mg of lipid-based extract daily, which almost no supplement on the market actually hits

Finasteride and dutasteride work on the same enzyme. They are not the same drug.
Finasteride blocks only Type II 5-alpha reductase.
Dutasteride blocks both Type I and Type II, suppressing DHT more aggressively but also disrupting neurosteroid production, which regulates mood, motivation, and sexual function.
Dutasteride has a half-life of 5 weeks, meaning it stays in your system for months after stopping and the withdrawal shedding is brutal and prolonged.
A study in the Journal of Sexual Medicine found 94% persistent low libido and 92% persistent erectile dysfunction after stopping finasteride, lasting an average of 40 months.

6 natural compounds for hair loss with actual published data behind them:
1.Saw palmetto 320mg daily, lipid extract (83% of patients showed increased density in RCT, 2020 systematic review)
2.Pumpkin seed oil 400mg daily (40% increase in hair count vs 10% placebo in 2014 RCT)
3.Rosemary oil topical (equivalent to minoxidil 2% at 6 months in 2015 RCT)
4.GHK-Cu copper peptide (promotes dermal papilla cell function and follicle angiogenesis, mechanistic evidence strong, large-scale RCTs limited)
5.Vitamin D3, dosed to blood result not a fixed dose (deficiency found in nearly 50% of hair loss patients across alopecia types)
6.Iron, corrected via ferritin testing not haemoglobin (deficiency associated with diffuse shedding across multiple large cohort studies)
None of these destroy your hormones.
All of them have published data.
That is the entire point.
7 things in your bathroom right now that could be making your hair loss worse:
1.Shampoo with sodium lauryl sulfate stripping your scalp lipid barrier every wash
2.Conditioner with dimethicone silicone building up on the scalp over time
3.Synthetic fragrance listed as one ingredient that legally hides up to 3,000 chemicals
4.Finasteride prescribed without a full androgen panel baseline beforehand
5.A hair supplement with a proprietary blend hiding whether the doses actually work
https://t.co/rwHBsMq2XQ water in the shower inflaming the scalp with every wash
7.The mirror you check your hairline in 30 times a day
50% of women with female pattern hair loss are vitamin D deficient.
Vitamin D receptors sit directly on hair follicle cells and regulate the signal that tells follicles when to grow and when to rest.
Without adequate vitamin D those signals break down and follicles prematurely enter the resting phase.
This finding comes from a 2024 systematic review and meta-analysis of every relevant study across PubMed, Embase, Scopus and Cochrane combined.
8 signs your hair loss is driven by a nutrient deficiency, not genetics:
1. Loss came on suddenly over weeks, not gradually over years
2. Hair is shedding diffusely across the scalp, not patterned at temples or crown
3. You are tired, cold, and your nails are brittle at the same time
4. You have been through a high-stress period in the last 3 months
5. You recently changed your diet significantly or lost weight fast
6. Your GP has never tested your ferritin, only your haemoglobin
7. You have never had your vitamin D or thyroid checked
8. You gave birth in the last 6 to 12 months
This type of hair loss is called telogen effluvium.
In most cases it is reversible.
Get the blood work first.

Biotin for hair loss is the biggest lie.
Here is what the actual evidence says.
A 2024 review in the Journal of Clinical and Aesthetic Dermatology searched all of PubMed for studies on oral biotin and hair growth in healthy individuals.
Three studies met inclusion criteria.
The highest quality study was double-blind, placebo-controlled, and found no difference between the biotin group and placebo.
Biotin only works for hair loss if you are genuinely biotin deficient, which is rare in people eating a normal diet.
The 10,000% RDA dose in your supplement is expensive, not effective.

10 reasons your hair is falling out that have nothing to do with genetics:
1.Low ferritin (iron stores, not just haemoglobin)
2.Vitamin D deficiency (affects nearly 50% of hair loss patients)
3.Low serum zinc
4.Thyroid dysfunction, especially subclinical hypothyroidism
5.Chronic psychological stress and cortisol elevation
6.Crash dieting or rapid calorie restriction
7.Protein deficiency (hair is almost entirely keratin)
8.Postpartum hormonal shift (oestrogen crash post-birth)
9.Medication side effects, especially antidepressants, statins, and hormonal contraceptives
10.Scalp inflammation from harsh detergents stripping the lipid barrier daily
Get blood work first. Then build a protocol.

Obsessively checking your hairline every day is making your hair loss worse.
Chronic psychological stress elevates cortisol, which suppresses Gas6 expression in the dermal papilla, keeping hair follicle stem cells locked in the resting phase.
Up to 70% of growing hairs can be prematurely pushed into the shedding phase during periods of chronic stress.
The 2 to 3 month delay between the stressor and visible shedding is why most people never connect the cause to the consequence.

5 reasons women’s hair loss gets worse before anyone helps them:
1. Doctors dismiss it as “just stress” without running a single blood test
2.Nobody checks ferritin - nearly 70% of women with diffuse hair loss are iron deficient
3.The shampoo they’re told to use contains the same sulfates stripping their scalp barrier
4.They’re prescribed corticosteroids for a condition that often resolves naturally in 6 to 12 months
5.The supplement they buy hides its doses behind a proprietary blend at $89 a month
Women’s hair loss is a health signal being ignored by a system that profits from the confusion.

8 things that will happen if you stick to a proper hair loss protocol for 6 months:
1.Months 1 to 2: Nothing visible. The shedding may temporarily increase. This is normal.
2.Month 3: Shedding begins to slow. This is the first real signal the protocol is working.
3.Month 4: New short hairs appear at the hairline and crown. Finer than before.
4.Month 5: Density improvement starts to become visible in photos taken in the same light.
5.Month 6: The difference between month 1 and now is unmistakable if you documented it.
6.Month 7 onward: Compounding. Each month adds on the last.
7.Month 12: You look back at the photos from the start and the change is undeniable.
8.Month 12+: Maintenance. This is not a course of treatment. It is a daily discipline.
There is no magic pill. There is only consistency compounding over time.

7 lies the hair loss industry tells you every day:
1.“Clinically proven” — from a company-funded study with no control group
2.“Advanced formula” — no formula disclosed, no doses published
3.“See results in 30 days” — the hair growth cycle is 90 days minimum
4.“Proprietary blend” — legal cover for underdosed ingredients
5.“Recommended by dermatologists” — one paid consultant counts
6.“Natural DHT blocker” — at what dose? From which extract? They won’t say
7.“Before and after photos” — different lighting, different angle, sometimes fibres applied
If they won’t publish every ingredient and every milligram, walk away.o
The 5 blood markers to test for hair loss:
1.Serum ferritin (not just haemoglobin - the full iron storage picture)
2.25-OH Vitamin D (nearly 50% of people with hair loss are deficient)
3.TSH, free T3 and free T4 (full thyroid, not just TSH alone)
4.Serum zinc (significantly lower in telogen effluvium and pattern hair loss patients)
https://t.co/5p1AksDA3v testosterone and SHBG (your androgen picture)
Results first. Protocol second.
In that order, every time.
