Some users have reported experiencing dryness, frizz, and a coarse texture after using the Strength Cure line, with one user's bleached hair snapping easily, leading to suspicion of protein overload. This occurs when hair receives too much protein relative to moisture, making it brittle. The Strength Cure system is designed with 'advanced anti-breakage technology' to restore up to 99% of hair’s original strength, which may involve protein-based treatments. To mitigate this, experts suggest alternating with deeply moisturizing conditioners or using a clarifying shampoo periodically to prevent build-up. Ensuring thorough rinsing of the rich formula is also crucial.

Yes, multiple users with thin and fine hair have found the Strength Cure line to be highly effective, even those who do not chemically process their hair. Some consider it a favorite for daily use. The formula is noted as being suitable for fine to medium hair types, enhancing natural shine and manageability. While generally well-received, a few users with fine, oily hair might find the rich formula leads to greasiness if not thoroughly rinsed, a common consideration with nourishing shampoos.

Reports from users indicate a concern about increased hair loss after using the Strength Cure shampoo and conditioner. Specifically, users with fine, straight, color-treated hair have noted significant shedding during showering and brushing, attributing the issue directly to the products. While forums lack controlled studies, these direct user accounts suggest a pattern. If you observe a marked increase in hair shedding after starting this product line, discontinuing use and consulting a dermatologist is advisable.
