Understanding the Root Cause: Why Do Hair Extensions Cause Hair Loss?

The Pulling Effect: Constant Tension on Your Scalp

This is the primary culprit. If braids are too tight or the weight of the extensions is excessive, hair follicles are constantly under tension, leading to poor circulation, damaged hair roots, and ultimately hair loss. This often manifests as a receding hairline, a widening parting, or permanent hair loss in the braided area.

The Full Shine Safety Protocol: Beyond manufacturing, Full Shine serves as a technical hub for professional stylists. Our extensions are engineered using a Scientific Weight-to-Tension Ratio. This means every weft is designed to distribute weight evenly across your natural hair, minimizing the risk of traction alopecia. We advocate for the ‘Two-Finger Comfort Test’—if a sew-in is too tight to slide two fingers underneath, it’s too heavy for your roots

Maintenance Mistakes: Poor Care and Rough Removal

Rough combing, improper washing methods (which can lead to fungal growth at the roots), and unprofessional, rough removal can all cause secondary damage to already fragile hair.

The Current Health of Your Natural Hair

If your hair is naturally fine and thinning, or you’re experiencing hair loss due to factors like postpartum or stress, your hair follicles are more fragile and less able to withstand external forces.

Expert Safety Rules During Your Appointment

Lab-Tested for Scalp Health: In our dedicated manufacturing facility, Full Shine Hair Wefts undergo rigorous stress-point testing. We ensure the hair fibers remain lightweight while maintaining maximum density. By controlling the entire production process, we eliminate the heavy chemical coatings often found in lower-quality hair that can irritate the scalp and lead to scratching or hair loss.

Your Daily Routine: Keep Your Roots Strong and Healthy

Wash with Care: How to Cleanse Your Scalp Gently

• Use a professional sulfate-free shampoo and gently massage your scalp with your fingertips (not your fingernails) to thoroughly cleanse the roots and braid base of your hair to prevent oil and product residue from clogging the follicles.

No Dampness Allowed: Why Keeping Your Scalp Dry is Key

• After shampooing, be sure to thoroughly dry your scalp with a hair dryer on low, cool air. A moist scalp fosters bacteria and mold, which can cause folliculitis.

Brush Smarter: Preventing Tangles Without the Tug

• Use a wide-tooth comb or a professional loop brush to gently comb your hair from the ends upwards. Patiently untangle any tangles and avoid pulling violently.

Give It a Rest: Why Your Hair Needs Regular Breaks

• It is generally recommended that sew-in extensions be installed for no more than 6-8 weeks. If they are not removed for an extended period, new hair growth will change the point of support, increasing the burden on the hair follicles.
