Surprised? It’s true. Hydrating and moisturizing are two terms that actually mean different things. While it is common for some consumers to assume that haircare and skincare products labeled, “moisturizing” are “hydrating” or vice- versa, each product actually serves a specific but different purpose when it comes to your skincare needs.
But why the confusion? The beauty industry is booming with numerous brands, an abundance of innovative products, and labels advertising ground-breaking ingredients you can encounter up and down the beauty aisles. Since brands use the terms “hydrating” and “moisturizing” interchangeably on various skincare and haircare products, it’s easy to get overwhelmed when choosing between which “moisturizing” and “hydrating” products are more suitable for your individual skin or hair type.
I get it. I have bought more products than I care to admit, without really knowing if they were ‘right’ for my skin and hair type. This is why knowing more about the products you use, can make all the difference in your hydration and moisturization goals.
So, What’s the Difference between Hydrating and Moisturizing?
According to dermatologists, hydrating refers to increasing the amount of water in your skin. However, moisturizing refers to preventing the loss of water from your skin. In an article posted by SHAPE, Meghan Feely, M.D., FAAD, a board-certified dermatologist in New Jersey and New York City, explains the difference as follows :
- “Hydrating products hydrate your skin cells, i.e. increase their water content.”
- “Moisturizing products, on the other hand, help to prevent trans-epidermal water loss—AKA moisture that evaporates from your skin—reinforcing your skin’s barrier function…”
How You Can Tell if Your Skin Needs Hydrating or Moisturizing
Is your skin dry? Dehydrated? Both?
Before choosing a hydrator or moisturizer, you must first identify your skin type and the root cause of your dehydration or dry skin by answering this question.
Board-certified dermatologist, Dr. Dhaval Bhanusali, gives some tips for determining whether your skin is dry or dehydrated in an article by skincare.com:
“Dry skin describes your skin type: it produces very little oil (sebum).”  Dr. Lortscher explains in SHAPE, that it is possible for our skin not to produce a lot of oil but still have normal levels of hydration or water. This would be an example of skin that is dry, but still hydrated. If this is the case for your skin, then a good moisturizer is what your skin needs to help lock in moisture. Your skin is most likely dry if you experience these symptoms: 
“Dehydrated skin is a skin condition that can make your skin look dull and lackluster…”  If left untreated it can also contribute to other skin issues like wrinkles, eczema and psoriasis, according to NYC dermatologist Dr. Hellman.  This means your skin lacks water and you should drink plenty of water throughout the day. Some signs of dehydrated skin are: 
- A rough/scaly texture
- Itchiness or skin tightness
- Excess Oil
Causes of Dry or Dehydrated Skin
Sorry to break the bad news, but although some external factors can be the culprit of your dry skin, it most likely is “hereditary and due largely to genetics” according to Dr. Hellman. 
Some external causes of dehydrated skin are:
- low water intake
- a poor diet
- large caffeine consumption
On the other hand, dry skin can be caused due to other factors including:
For this reason, dermatologists suggest keeping your skin consistently moisturized as it will help lessen the damage to your skin over the years.
The “It” Ingredients to Kiss Dry and Dehydrated Skin Goodbye!
“The best ingredient for dry or dehydrated skin is hyaluronic acid, due to its ability to hold up to 1000 times its weight in hydration,” says Los Angeles esthetician, Melissa Lekus,as she explains in an article by Healthline.  Similarly, David Lortscher, M.D., a board-certified dermatologist also recommends using hyaluronic acid in an article by Shape, stating: “Using hyaluronic acid has shown a positive effect on the appearance of wrinkles and skin elasticity due to its moisture-binding properties, which help keep your skin plump and dewy…” 
Dr. Hellman, a New York City dermatologist, recommends alpha hydroxy acids (AHAs) such as lactic acid and glycolic acid for their ability “to encourage hydration and cell turnover.”  Other hydrating ingredients to look for in products “that deliver water to the cells directly” are propylene glycol, urea, or glycerin, and aloe. 
For moisturizing the skin, dermatologists recommend products that contain ingredients including: ceramides, glycerin, or omega-fatty acids. Facial oils are also a great source of moisture. 
Avoid these Ingredients for Dry or Dehydrated Skin!
Dermatologists warn about using ingredients that may worsen your dry or dehydrated skin. Look out for these ingredients and avoid products containing them as they soak up the skin’s natural oils leaving your skin over-dry by stripping the top layer of the epidermis. These ingredients may cause your skin to become flaky or scaly:
- salicylic acid
- tea tree oil
Causes of Dry Hair
Hair that doesn’t receive or retain enough moisture, loses its shine and becomes frizzy and dull.
Does your hair feel brittle or rough? There may be several causes leading to your dry hair concerns including, environmental conditions, hair care habits, and your physical health. 
Here are some of the environmental conditions that can cause dry hair include:
- living in a dry, hot climate
- spending a lot of time in the sun or wind
- frequently swimming in chlorinated or salty water
Other causes of dry hair can be brought on by your hair care practices. For example, ask yourself these questions regarding your hair routine:
- Do you wash your hair too often?
- Do you use harsh shampoos, conditioners, or styling products?
- How often are you dying or chemically treating your hair?
- Are you blow-drying your hair daily?
- Are using electric curling irons, straighteners, or curlers?
Another cause of dry hair may be related to your health. Some underlying health issues that can affect your hair’s ability to retain moisture include:
- Anorexia nervosa: An eating disorder, anorexia nervosa can lead to malnutrition. It can cause dry and brittle hair, along with more serious complications. 
- Hypoparathyroidism: If you have hypoparathyroidism, the parathyroid gland in your neck produces too little parathyroid hormone, which decreases the level of calcium in your blood. Calcium is a key nutrient for healthy hair, as well as bones, teeth, and other tissue. 
- Hypothyroidism: With hypothyroidism, your thyroid glands don’t produce enough thyroid hormones. Dry and brittle hair is one of the early symptoms of this condition.
