Why Your Hair Isn’t Growing (And What to Do About It)

Why Your Hair Isn’t Growing (And What to Do About It)

Stuck at the Same Length? You're Not Alone

If you feel like your hair just won’t grow past a certain point, even though you’re doing everything right, you’re not imagining it.

Hair that refuses to grow is often the result of an internal imbalance. The issue usually lies at the follicle level, where hair is either stuck in the wrong phase or lacking the nutrients it needs to grow properly.

Let’s break down the science.

The Three Stages of Hair Growth

  1. Anagen (Growth Phase)
    This phase lasts two to seven years and is when hair actively grows from the root.

  2. Catagen (Transition Phase)
    A short period of about two to three weeks when the follicle shrinks and prepares to rest.

  3. Telogen (Resting Phase)
    Lasts about three months. Hair sheds naturally during this stage.

If your follicles remain in the telogen phase, they won’t return to growth. Stress, hormone shifts, inflammation, and nutrient deficiencies are often the reason.

Common Reasons Hair Growth Stops

1. Chronic Stress or High Cortisol

Persistent stress increases cortisol levels, which can shrink follicles, push hair into the resting phase, and delay regrowth.

Strand Science Hair Revival Complex includes adaptogens clinically shown to reduce cortisol and rebalance the body.

2. Protein or Collagen Deficiency

Hair is made primarily of keratin, a protein. Without sufficient intake of key amino acids, collagen, and co-nutrients like vitamin C, the body struggles to build strong hair.

StrandScience Hair Revival Complex provides marine collagen, L-Lysine, and supporting nutrients for internal hair structure.

3. DHT Sensitivity

DHT, a byproduct of testosterone, can miniaturise hair follicles and reduce their ability to grow strong, thick strands.

StrandScience Hair Revival Complex includes saw palmetto extract, which supports healthy DHT regulation.

4. Thyroid or Iodine Imbalance

Low iodine intake may impair thyroid function. The thyroid plays a central role in regulating the hair growth cycle.

StrandScience Hair Revival Complex includes iodine from kelp to support optimal thyroid balance.

5. Gut Health and Nutrient Absorption

Gut issues can disrupt nutrient absorption and trigger systemic inflammation, both of which affect hair growth.

StrandScience Hair Revival Complex includes probiotics and prebiotic inulin to support gut health and reduce inflammation.

How to Restart Growth From the Root

  1. Address internal factors including stress, nutrient gaps, and hormone imbalances

  2. Support your follicle structure and hair-building process

  3. Improve gut health for better nutrient delivery

  4. Be consistent over a minimum of 90 days to support the natural hair growth cycle

Strand Science Hair Revival Complex is designed to support all of these systems in one formula.

Soooooooo... 

If your hair feels stuck, the answer is rarely found in surface-level treatments. True results begin at the root, and that means starting from within.

StrandScience Hair Revival Complex supports the body’s ability to grow hair stronger, longer, and with greater density by targeting the systems that drive growth cycles.
