All Monday products are paraben- and SLS-free, making them safe to use on color-treated hair. While I had a great experience with this formula, a few of the ingredients in the Smooth range don’t pass our ByrdieClean Beauty Pledge. Both the shampoo and conditioner contain BHT (butylated hydroxytoluene), a commonly used preservative linked to skin irritation and hormone disruption. I didn’t experience any reactions, but if your scalp tends to be extremely sensitive, I would recommend doing a small patch test before incorporating this duo into your regular routine, or go for a more scalp-focused set. The Aveeno Pure Renewal Gentle Shampoo is one of the best options for all hair types, while the Aveeno Cotton Blend Shampoo is suitable for colored hair. However, this is not the right choice if you have 4c hair and want a product to tame it down. The maximum it can do for your hair is to cleanse it properly. Licensed cosmetologist and master hair stylist, Laura Dale adds, “Many people are sensitive to common ingredients found in shampoos like sulfates and parabens. If you feel your scalp is sensitive or irritated, switching to a gentle shampoo can really help.” After using it for over 3 months, I can say that it’s one of the top shampoos. Monday shampoo cleans and nourishes the hair without any damage.

Overall, all of the Monday shampoos are safe to use, and they are formulated for people with damaged hair. Limited information: Some consumers may find that there is limited information available about the ingredients in Monday Haircare products or the manufacturing process. Affordable: Monday Haircare is a relatively affordable haircare brand compared to some of the high-end salon brands available. Opt for color-safe shampoo formulas for colored hair. Avoid SLS, SLES, petrochemicals, sodium chloride, and parabens that fade the color and vibrancy of the shade.. For hair and scalps that need a little extra TLC, MONDAY Haircare’s GENTLE line is formulated with nourishing and supportive ingredients such as shea butter, coconut oil, vitamin E and panthenol. It also contains a lower percentage of fragrance than our other lines.Editor’s Note: We reviewed this article on October 30, 2023.

As my skin is a combination and not that sensitive, I did not see any effects. Another reason why I recommend this shampoo and consider it a great product is because it is vegan and cruelty-free. Just as their names imply, Smooth Shampoo and Conditioner both impart soft, shiny hair and cut down on frizz. I usually can’t even be bothered to use conditioner and try to find extra hydrating shampoos to make up for that skipped step, but I’ve happily used both bottles every time I wash my hair. I’m a fan of how the combined formulas give a glossy finish to my hair without weighing down my waves. Although this isn’t the volumizing duo, my air-dried hair still maintains tons of lift and movement (and smoothness, of course). To enhance the results, I gently towel-dry with my trusted Aquis Rapid Dry towel and sleep on a silk pillowcase to cut down on tangles and preserve shine. (The ones from Branché are amazing and hold up best after multiple washes.)

Moreover, many recently took over the internet and complained about the silicone in Monday shampoo. Though BHT is used commonly, it is responsible for irritation. It can also result in hormonal issues.

Though it is good enough that Monday shampoos don’t have SLS and parabens, silicone is also a potent chemical. I couldn’t go through this Monday Haircare review without mentioning what customers didn’t like about the products. Some users reacted negatively to the shampoos, saying their scalp felt irritated. However, this could be due to one ingredient rather than the entire shampoo concoction.
