Dry Hair: Causes, Treatments & Tips

Dry hair can be frustrating to manage, leading to brittleness, split ends, and a lacklustre appearance. But by understanding the root causes and finding the right treatments, you can restore moisture and get the healthy, vibrant hair you dream of.

Causes of Dry Hair

 

First, let’s think about some of the things that might be drying your hair out, so that you can work towards preventing and reducing any dryness.

 

The fact is, there isn’t always a clear-cut answer. Dry hair can be the result of a range of internal and external factors that disrupt the hair’s ability to retain moisture.

Let's dive deeper into some of the most common reasons for dry hair:

  • Lack of natural oils

  • Weather and seasons

  • Styling and treatments

  • Hair porosity

  • Hormones and health

 

  • Lack of Natural Oils

     

Natural oils produced by the scalp play a vital role in maintaining hair hydration. Factors such as overwashing, using shampoos with harsh sulphates, or naturally low sebum production can strip these oils, leaving hair dry, frizzy, and prone to breakage.

 

  • Environmental Factors

     

  • UV Exposure: Overexposure to sunlight weakens the hair shaft and reduces moisture retention, leading to dryness and increased vulnerability to split ends.

  • Wind and Humidity: Windy conditions cause tangling, while humidity exacerbates frizz, further damaging hair strands over time.

  • Seasonal Changes: Winter air, with its low humidity, often causes dryness, while summer activities like swimming in chlorinated water strip moisture.

 

  • Heat Styling and Chemical Treatments

     

Using tools like flat irons, curling wands, and blow dryers frequently can deplete hair of moisture. Chemical treatments - bleaching, perming, and colouring – break down the cuticle, leaving the hair porous and vulnerable to dehydration.

 

  • Hair Porosity

     

Hair porosity significantly impacts how your hair absorbs and retains moisture:

  • Low Porosity: The cuticle layers are tightly packed, making it difficult for moisture to penetrate. While this prevents excessive moisture loss, it also means hydration products may not absorb effectively.

  • Medium Porosity: Ideal porosity allows moisture to be absorbed and retained efficiently.

  • High Porosity: Often caused by damage, the cuticle layers are widely spaced, leading to rapid moisture loss and dry, brittle hair.

 

  • Hormonal Changes and Health Conditions

     

Fluctuating hormones due to pregnancy, menopause, thyroid imbalances, or other hormonal conditions can lead to changes in scalp oil production. Additionally, other health concerns like anaemia often correlate with dry, lacklustre hair.

 

Effective Treatments for Dry Hair

 

Treating dry hair requires a blend of the right products, targeted care routines, and healthy habits. Here are tried-and-true methods to combat dryness.

 

  • Moisturising Hair Masks

     

  • A weekly moisturising hair mask can work wonders. Opt for masks such as the L'Oréal Professionnel Absolut Repair Resurfacing Mask which offers the ultimate professional deep resurfacing experience for damaged and dry hair while ensuring the hair is not weighed down, delivering up to 77% less surface damage2and up to 7x more shine3.

 

  • Gentle Shampoos and Conditioners

     

Switch to sulphate-free shampoos and conditioners formulated for dry hair. These products cleanse without stripping essential oils.

Top Picks:

 

  • Limiting Heat & Sun’s UV Exposure 

     

Excessive heat can damage hair, so limit heat styling whenever possible and embrace air drying. When heat styling is necessary, always apply a heat protectant spray, such as L'Oréal Professionnel Metal Detox Oil,  which shields hair from thermal damage up to 230°C1. Furthermore, remember to protect your hair from the sun's harmful UV rays by wearing a hat or using leave-in treatments that contain UV filters. These preventative measures will help maintain your hair's health and shine.

 

  • Proper Hair Care Routine

     

Daily care can make a big difference. Use hair treatments like L'Oréal Professionnel Metal Detox Oil or lightweight oils like argan or jojoba oil. Apply to ends for up to 87% less hair breakage1and up to 2x shinier hair1.

 

Preventing Dry Hair in the Future

 

Prevention is always better than cure. Incorporate these lifestyle changes to maintain well-hydrated, healthy hair.

 

  • Avoid Over-Washing

     

Washing hair two to three times a week preserves natural oils. Between washes, opt for dry shampoos to maintain freshness without over-cleansing.

 

  • Healthy Diet and Hydration

     

A healthy diet and proper hydration are crucial for strong, lustrous hair. Essential nutrients play a vital role in hair growth and overall health. Incorporate foods rich in vitamin B-complex, such as eggs and leafy greens, to support keratin production, the protein that makes up hair. Omega-3 fatty acids, found in salmon and walnuts, promote a healthy scalp, and encourage hair growth. Vitamin E, present in avocados and almonds, acts as an antioxidant, protecting hair follicles from damage. Finally, ensure you drink at least two litres of water daily to keep your scalp hydrated and your hair looking its best.

 

  • Hair-Friendly Accessories

     

Taking care of your hair goes beyond just the products you use. Incorporating hair-friendly accessories and practices into your routine, such as using silk pillowcases and microfiber towels, can significantly improve your hair's long-term health and appearance. Silk pillowcases create a smooth surface that reduces friction, minimizing breakage, tangles, and moisture loss while you sleep. Similarly, microfiber towels are gentler and more absorbent than traditional cotton, reducing damage and frizz for smoother, healthier-looking hair. To further protect your hair, consider using the L'Oréal Professionnel Metal Detox Oil,  which protects against the drying effects of metals found in hard water, locking in moisture and enhance your hair's overall health to smooth the cuticle, reduce frizz, and protect against environmental stressors.

By using gentle products, hydrating masks, and adopting protective habits, you can restore your hair's moisture and radiance. Remember to stay consistent and make gradual lifestyle changes to ensure lasting results.
