The tip with the strongest case is the least exciting one: get bloodwork before you buy anything. Last week, a post asking for “tried and tested methods to stop hair loss” passed 2 million views on X. Here is how its most-repeated answers hold up.
- 1. Get bloodwork first: strong evidence
- 2. Eat enough protein: strong evidence
- 3. Eat a daily seed mix: some evidence
- 4. Massage your scalp daily: some evidence
- 5. Use rosemary oil: limited evidence
- 6. Use ketoconazole shampoo: some evidence
- 7. Apply homemade onion, curry leaf or fenugreek oils: weak evidence
- 8. Detangle from the ends up: good for breakage, not hair loss
- 9. Minoxidil: strongest evidence of any treatment here
- Myths that went viral this week
- When to see a dermatologist
1. Get bloodwork first: strong evidence
Low iron stores, low vitamin D and thyroid problems are all linked to hair shedding, and a blood test is the only way to know. It was the most-repeated reply in the thread. Several people said their shedding slowed once a deficiency was corrected. Ask your doctor for ferritin, vitamin D and a thyroid panel. Our guide to vitamin D and curly hair covers the vitamin D link.
2. Eat enough protein: strong evidence
Hair is mostly keratin, a protein, and the body cuts supply to hair first when food is short. Crash diets and very low protein intake are a common trigger for telogen effluvium, the diffuse shedding that shows up two to three months after the cause.
3. Eat a daily seed mix: some evidence
The seeds help as part of a diet, but no study shows that eating seeds regrows hair. The pumpkin seed research people cite used pumpkin seed oil capsules, not toast toppings. Seeds supply zinc, iron and protein. That matters if you’re low on them, and does little if you’re not.
4. Massage your scalp daily: some evidence
A small 2016 study of nine men (Koyama et al., Eplasty) found that four minutes of scalp massage a day for 24 weeks increased average hair thickness from 0.085 mm to 0.092 mm. It had no comparison group, so it can’t promise results, but massage costs nothing and carries no risk. Do it on dry hair or while applying oil.
5. Use rosemary oil: limited evidence
The rosemary oil claims trace back to one 2015 trial (Panahi et al., Skinmed). It randomly assigned 100 people with pattern hair loss to rosemary oil or 2% minoxidil. After six months, hair counts had risen in both groups with no significant difference between them, and scalp itching was more common with minoxidil. There was no placebo group and no larger trial has repeated it, so treat it as promising but thin. Dilute the oil in a carrier oil before it touches your scalp; NOW 100% Pure Rosemary Oil is a pure essential oil to mix your own. Our comparison of rosemary, castor, coconut and argan oil explains what each oil can and can’t do.
6. Use ketoconazole shampoo: some evidence
Ketoconazole 2% is an anti-fungal that treats dandruff and an inflamed scalp. Small studies suggest it may also help with pattern hair loss. Use it once or twice a week and leave it on for a few minutes before rinsing. Read whether ketoconazole helps hair loss before you buy.
7. Apply homemade onion, curry leaf or fenugreek oils: weak evidence
These remedies are traditional, and the research behind them is small or old. They are unlikely to hurt an intact scalp. Patch-test first: onion and garlic preparations can irritate skin. Our article on ancestral hair ingredients covers the evidence for each one.
8. Detangle from the ends up: good for breakage, not hair loss
Combing ends first and detangling before you shower reduces breakage. Breakage is hair snapping along its length; shedding is hair falling from the root. Detangling helps the first and does nothing for the second. If the hairs you’re losing have a small white bulb at one end, they shed from the root.
9. Minoxidil: strongest evidence of any treatment here
Minoxidil has the most clinical evidence of any treatment in the thread. It needs consistent use, and the oral version needs a prescription. Speak to a pharmacist or dermatologist before starting. Our minoxidil guide explains the early shedding phase that scares people off.
Myths that went viral this week
“Masturbation causes hair loss.” A post asking this passed 3.5 million views. No clinical evidence supports it. Pattern hair loss is driven by genetics and hormones, not sexual activity.
“One oil will reverse baldness.” No oil has been shown to regrow hair on a scalp that is already bald. Oils may support the scalp around existing follicles.
When to see a dermatologist
See a dermatologist if you’re losing hair in patches, if your scalp is red, scaly or painful, or if shedding lasts more than three months. Patches and scaling can point to conditions that shampoo won’t fix.
