Over six weeks of use, this shampoo enhanced my hair's thickness appearance, providing a fuller look despite minimal new growth, and I recommend it for similar hair loss concerns.


This is a review from Amazon.com about product:

I Improved My Hair Thickness with This Shampoo


I have been using this and the shampoo/ conditioner for about 6 weeks. I don’t see much new growth yet but I use it on my hair leanth prior to blow drying on low heat only and I definitely noticed improvement in the thickness “look”. I lost half my hair the months prior I think from stress and from having COVID months prior.


It is heart breaking for us women but hang in there. My doctor put me on medication and a prescription oil that is a cortisone product. If you’re scalp feels irritated or burning as mine did I recommend seeing a doctor immediately.


The scalp oil was a big help.


Good luck everyone.


Shampoo Basics & Tips


Understanding Hair Loss and Shampoo Benefits


Hair loss can be distressing, especially for women, as mentioned in the review. Common causes include stress and illnesses like COVID-19. Stress-induced hair loss, known as telogen effluvium, occurs when significant stress pushes hair follicles into a resting phase, leading to shedding months later. COVID-19 has been linked to temporary hair loss due to the body's inflammatory response and physical stress during recovery. Using a shampoo designed for thickness can help improve the appearance of hair by adding volume and strengthening strands, though it may not directly stimulate new growth overnight. Ingredients like proteins and vitamins in shampoos can coat the hair, making it look thicker.


Scalp Health and Medical Advice


If your scalp feels irritated or burning, as the reviewer experienced, it could indicate conditions like seborrheic dermatitis or allergic reactions. Cortisone-based products, such as the prescription oil mentioned, contain corticosteroids that reduce inflammation and itching. Always seek medical advice for persistent scalp issues, as self-treatment might worsen problems. Regular use of gentle shampoos can maintain scalp health by balancing oil production and preventing buildup.


Daily Hair Care Tips for Thickness


To enhance hair thickness, avoid high-heat styling, as the reviewer did by blow-drying on low heat. Incorporate a balanced diet rich in biotin and iron, and consider supplements if deficient. Common questions include how long it takes to see results—typically 4-6 weeks, as in the review—and whether shampoos can reverse hair loss. While they can improve appearance, underlying causes may need medical intervention.
