Why is My Hair So Dry? 9 Causes of Dehydrated Strands

If you’ve ever run your fingers through your hair and asked, “Why does my hair feel like straw?” your hair might be thirsty for hydration.

Dry hair lacks the essential oils and moisture it needs to stay healthy and hydrate. What does dry hair look like? If your mane feels rough, dull, or tangles easily, chances are it needs a hydration boost.

As for what the main causes of dry hair are, here’s the scoop:

Environmental factors

Sun exposure, wind, and pollution strip moisture, while heat and humidity overburden your locks with moisture, causing dryness as it evaporates.


Even the best hair care routine can’t override your genetic code. For example, curly or coily hair tends to have higher porosity, absorbing moisture faster and requiring more intensive hydration. Contrast that with straight, low-porosity hair which takes more time to absorb, but retains moisture better. Genetics underscore the need for customized hair care.


Overdoing it with heat and chemical treatments can severely dehydrate your hair. These practices strip away natural oils and moisture, leaving locks brittle and lifeless. Repeated exposure to high temperatures and harsh chemicals breaks down hair structure, exacerbating dryness and damage.


Overwashing your hair, particularly with harsh shampoos or in hard water, can also lead to significant dryness. Sure, it removes dirt and oil, but this excessive cleaning never gives your natural oils a chance to reproduce, depleting your hair’s natural moisture that’s essential for health. Hard water compounds the issue by depositing minerals that build up and further dry out your tresses.

Product buildup

In contrast, not washing your hair enough can lead to product buildup, ironically triggering dryness. Accumulated residue from styling products can block moisture from penetrating the hair shafts, leaving your strands greasy yet dehydrated.

Chlorinated water

Nothing beats a dip in the pool on a hot summer day. The catch? Regular exposure to chlorine can seriously dehydrate hair. It not only removes protective natural oils but also compromises the hair's cuticle, causing moisture to escape. This results in dry, brittle hair susceptible to damage and breakage.


It’s a common misconception that air drying is the healthiest way to dry your hair, but that’s not necessarily true. Leaving hair wet for extended periods can cause significant damage due to prolonged swelling of hair fibers. This swelling impacts your hair’s cells, weakening them and making hair more prone to dryness.

Poor diet

A diet lacking essential nutrients like vitamins, minerals, and fatty acids directly impacts the health and hydration of your hair. That means adequate nutrition is a must for natural moisture balance and preventing dry hair.

Health issues

Sometimes, repairing dry hair means addressing a deeper issue affecting your scalp's ability to function correctly. Conditions like hypothyroidism or hormonal imbalances can reduce oil production, directly impairing hair’s moisture.

Understanding what causes dry hair is an essential first step in identifying the issue, and the next order of business is: how do you hydrate dry hair? 


10 Tips for Revitalizing Dry Locks

Not sure which culprit is the root of your hair troubles? No worries. It might take some tweaking of your routine or diet, but with a little guidance and trial and error, you'll find what works in time.

Ready to revive your hair’s hydration? Here are 10 dry hair remedies to bring back the moisture to your tresses:

1. Hydrate inside and out

Proper hydration, both internally and externally, is crucial for combating hair dryness. Drinking plenty of water nourishes your strands from within while moisturizing hair products ensure they retain essential moisture, keeping them soft and healthy.

2. Eat a nutrient-rich diet

Certain vitamins and minerals play a major role in maintaining hair hydration and overall health. Here are some key nutrients to keep your hair happy and healthy:

  • Protein
  • Vitamins A, C, and E

  • Biotin

  • Niacin

  • Zinc

  • Iron

  • Magnesium

  • Omega-3 fatty acids

3. Tailor your wash routine to your hair type

Tailoring your washing and conditioning routine to your hair type, such as using co-wash for curly hair or washing less frequently for fine hair, can significantly enhance hydration. For an added boost, incorporate hydrating hair treatments, like YA-MAN's Deep Moist Repair Treatment , to deeply nourish and rejuvenate dry, dehydrated locks.

4. Keep up with regular trims

Regular trims prevent split ends from worsening, which can lead to breakage and more hair dryness. By trimming your ends regularly, you can keep them fresh, reduce damage, and help maintain overall moisture and hair integrity.

5. Use nourishing ingredients

Incorporating hydrating hair treatments with Argan, Castor, or Olive Oil into your routine can significantly improve hydration and strength. Pair that with ingredients like Glycerin, Keratin, and Aloe Vera to seal in moisture, repair damage, and protect hair from potential stress.


6. Choose ionic hair dryers and minimal heat

Today's innovative hair tools, like ionic blow dryers, are revolutionizing how we care for our mane. Ionic hair dryers help cut drying times and reduce heat damage, while low heat settings (and thermal protection ) reduce the harsh effects of heat styling on your hair's health.

Our go-to? The YA-MAN SPA STYLER® Blow Dry + Scalp Massage combines quick-drying ionic technology with Red Light Therapy and scalp massage, boosting volume, shine, and smoothness while soothing and stimulating the scalp.

7. Always use a heat protectant

Heat damage strips hair of essential moisture and natural oils, promoting dry, brittle hair. Heat (or thermal) protectants, like our Moist Hold Repair Oil , form a barrier on your locks, shielding them from the adverse effects of high temperatures.

8. Curb hair’s exposure to chlorine

Limiting hair's exposure to chlorine can keep thirsty, brittle hair at bay. Consider a swim cap, rinse your hair with fresh water before and after each swim, and apply a leave-in conditioner to protect your strands.

9. Adopt healthy habits

Healthy lifestyle habits like managing stress, a balanced diet, adequate hydration, and hair health supplements (under the guidance of your dermatologist or Primary Care Physician can significantly improve the life of your hair.

10. Talk to a dermatologist

If your hair still feels dry after some trial and error, consider seeing a Dermatologist. A healthcare professional can help you determine if any underlying issues are at play and guide you toward the best treatment.
