How Do You Know If Your Hair Is Healthy or Damaged?

AspectHealthy HairDamaged Hair

Hair ElasticityVery elastic and hard to breakNot elastic and breaks easily
Split EndsAbsentPresent
Hair FrizzAbsentPresent
Hair AppearanceShiny and smoothDull and frayed

Looking for these telltale qualities in your hair can let you know if your hair is healthy or damaged:

1. Hair Fall

Hair fall is a natural part of the hair growth cycle, where old hair sheds to make way for new growth. While hair fall is not a sign of damaged hair, losing more than 100 hairs per day may indicate a problem and may point to hair damage. (2)(3)

Keep in mind that hair fall can also be due to medical issues such as thyroid disorders, polycystic ovarian disease (PCOD), alopecia areata, pregnancy, and stress and not only due to poor hair health. (4)(5)

Remedy: Regular hot oil massages can improve blood flow to the hair follicles, providing essential nutrients and oxygen to prevent hair fall. (6)

2. Hair Elasticity

Healthy hair is naturally elastic, capable of stretching and returning to its original form without any breakage. Hair is made up of keratin fibers that are responsible for its flexibility.

Unhealthy hair is prone to breakage when stretched, which points toward notable hair damage. (7)(8)

Remedy: A diet rich in omega-3 and omega-6 fatty acids can moisturize hair and maintain scalp health, enhancing hair elasticity. (9)

3. Split Ends

When the protective outer layer of hair becomes damaged, split ends or hair fraying may occur. Hair strands appear as splits at the hair ends, creating a messy appearance and increasing susceptibility to breakage. (1)

Remedy: Coconut oil, with its moisturizing properties and fatty acids, can nourish hair and prevent split ends and thus enhance hair health. (10)(11)

4. Hair Frizz

Smooth hair often indicates healthy hair. In contrast, excessive frizziness can be a sign of unhealthy hair, often caused by frequent heat styling or chemical hair treatments.

Dry and damaged hair tends to become frizzy. (12)(13)

Remedy: A yogurt and honey mask can help tame frizzy hair. These ingredients have excellent hydrating properties that condition and smooth hair. (14)

5. Hair Appearance

Healthy hair is smooth and shiny, reflecting its structural integrity. Pollution and chemical damage can strip away shine, leaving hair looking dull and weak. (15)

Remedy: Using egg masks can nourish and add shine to dull hair, as eggs contain peptides that promote hair health. (16)

Most-Asked Questions

Many aspects of damaged hair such as hair loss can be hereditary.

Final Word

Knowing about common hair issues and learning effective remedies can help you maintain healthy hair and say goodbye to damaged hair. Welcoming the right hair care practices in your hair care routine can lead to improved hair health and better hair appearance.
