Jumbo DAMAGE SHIELD pH protective shampoo
Color-safe protective shampoo maintains hair health + strength - now in a jumbo size
A color-safe, pH-optimized shampoo with the patented K18PEPTIDE™ to effectively cleanse while maintaining hair health and protecting hair from damage. pH-optimized formula helps reduce excess swelling of the hair cuticle during washing to help prevent frizz, preserve color, and enhance shine. Scalp microbiome-friendly and gentle enough to use every time you cleanse.
Is the formula of the DAMAGE SHIELD pH protective shampoo different from the PEPTIDE PREP™ pH maintenance shampoo?
No, the formula of the DAMAGE SHIELD pH protective shampoo is not different from the PEPTIDE PREP™ pH maintenance shampoo. Just the name has changed, the formulation you know and love is the same.
What makes the DAMAGE SHIELD pH protective shampoo special?
The DAMAGE SHIELD pH protective shampoo delivers healthier hair and scalp after just one wash. Its optimized pH helps maintain the hair cuticle, preventing excess water from entering the hair, which can cause damage, dullness, frizz, and tangling. With this shampoo, your color is maintained, hair feels strong, healthy, looks smooth with less frizz, and is easier to style with less tangles. This formula moisturizes hair without weighing it down, and preserves the scalp microbiome for a healthier-feeling scalp and a gentler cleanse. Coupled with the DAMAGE SHIELD protective conditioner, these formulas shield your healthiest hair from daily damage.
When do I use the DAMAGE SHIELD pH protective shampoo?
This pH-balanced formula is gentle enough to use every time you cleanse, delivering healthier hair and scalp after just one wash.
Why do I need both shampoos?
You need both shampoos to deliver the most effective clean while maintaining your hair + scalp health. Detox shampoo is engineered for less frequent heavy-duty washing, and DAMAGE SHIELD pH protective shampoo (previously pH maintenance shampoo) is engineered for frequent washing.
pH-optimized formula prevents frizz, dullness + tangles for everyone.
Safe to use every time you wash.
1. Massage into hair, focusing on scalp.
2. Thoroughly rinse.
3. Repeat as needed.
For best results, follow with DAMAGE SHIELD protective conditioner.

To go along with the leave-in treatment, I started using their shampoo, and it is the perfect pairing! A lot of repairing shampoos tend to weigh my hair down or leave a heavy residue, but this one leaves my hair feeling incredibly clean, light, and soft. It’s gentle enough that it doesn't strip my hair, but it still manages to get rid of all the daily buildup. It creates the perfect, clean canvas for the leave-in mask to really do its job.

I purchased the mini size because it’s the first time I’m using this brand, and I wanted to see how well it worked for my hair before committing to a regular sized bottle.
Because my hair is fine and on the shorter side, I’m able to get multiple uses from this product.
And it smells amazing!
I recommend it
