Water in Japan

If you've arrived in Japan and noticed your hair is falling out more than usual, know that you're not alone. Many Brazilians face this problem, and the culprit might literally be coming from your shower.

Important: This article provides tips to alleviate the problem, but we always recommend consulting a specialized doctor (皮膚科 - dermatologist) to investigate the specific causes in your case.

Why Does Japan's Water Affect Hair?

Japanese water has unique characteristics that can harm hair accustomed to Brazilian water:

• "Hard" water with high calcium and magnesium content

• Chlorine residues (used in water treatment)

• Different pH than what our hair is used to

• Specific mineral content depending on the region

The result: Dull, brittle hair, irritated scalp, and increased hair loss.

Washing Care

1. Pre-wash:

• Brush dry hair to remove tangles

• Apply coconut oil to the ends (15 minutes before)

2. Washing:

• Use warm water (never hot)

• Massage scalp with finger pads

• Rinse thoroughly

3. Post-wash:

• Condition only from ears down

• Rinse with cooler water to close cuticles

• Never sleep with wet hair

Extra Care That Makes a Difference

When to See a Dermatologist?

Seek professional help if:

• Hair loss persists after 3 months of care

• Visible bald spots appear on the scalp

• There is itching, redness, or flaking

• Hair loss is accompanied by other symptoms

In Japan, look for:

• 皮膚科 (Hifuka - dermatologist)

• Through health insurance (national or private)

• Ask for a referral at 内科 (general practitioner) first

Products to Avoid

❌ Shampoos with SLS (Sodium Lauryl Sulfate)
❌ Very hot water in the shower
❌ Hair dryer on maximum heat
❌ Products with alcohol
❌ Combing wet hair

Dietary Changes

Water isn't the only culprit. The Japanese diet might lack important nutrients:

Include in your diet:

• Nuts (rich in selenium)

• Fatty fish (omega-3)

• Dark green vegetables (iron)

• Eggs (biotin)

Consider supplements (after medical consultation):

• Biotin

• Zinc

• Vitamin D

Conclusion: Patience and Persistence

Improving hair quality in Japan is a process that requires:

1. Routine change (filter + appropriate products)

2. Time (3-6 months to see results)

3. Consistency (don't give up after 1 month)

Remember: Every head of hair is unique. What works for one may not work for another. Experiment, adapt, and above all, consult a specialist if the problem persists.
