保湿シャンプー vs ボリュームアップシャンプー：あなたの髪質に合うのはどっち？

Choosing the right shampoo can feel overwhelming when faced with endless options on the shelf. Two of the most popular categories—moisturizing shampoo and volumizing shampoo—serve very different purposes, yet many shoppers grab whichever bottle looks prettiest. Understanding the difference between these two types is essential for achieving healthy, great-looking hair every wash day.

Moisturizing shampoos are designed to hydrate and soften strands, making them ideal for dry, damaged, or curly hair. Volumizing shampoos, on the other hand, focus on lifting roots and adding body, which works wonders for fine or limp hair. In this guide, we break down the key differences, help you identify your hair type, and recommend the best shampoo for your unique needs.

What Is Moisturizing Shampoo?

Moisturizing shampoo is formulated with hydrating ingredients like glycerin, natural oils, and aloe vera that help replenish moisture lost from styling, environmental factors, or frequent washing. These shampoos typically have a creamier texture and produce a rich lather that gently cleanses without stripping the scalp of its natural oils. They are especially beneficial for hair that feels dry, brittle, or rough to the touch.

For those with curly, coily, or color-treated hair, moisturizing shampoo can be a game-changer. It helps reduce frizz, improve elasticity, and restore softness. If your hair tends to tangle easily or feels straw-like after washing, switching to a moisturizing formula can make a noticeable difference. Many moisturizing shampoos also contain proteins or ceramides to strengthen the hair shaft while hydrating.

• Best for: dry, curly, coily, color-treated, or damaged hair
• Key ingredients: glycerin, coconut oil, shea butter, aloe vera, argan oil
• Avoid if: you have very oily or fine hair that gets weighed down easily

What Is Volumizing Shampoo?

Volumizing shampoo is designed to add lift and body to hair by cleansing the scalp thoroughly and removing excess oil, product buildup, and residue that can flatten strands. These shampoos often contain lightweight polymers or proteins that coat each hair strand, making it appear thicker and fuller. They typically produce a lighter lather and may leave hair feeling slightly squeaky clean.

People with fine, thin, or limp hair often find volumizing shampoo essential for achieving a bouncy, salon-worthy look. It can also help extend the time between washes by keeping roots fresher longer. However, because volumizing shampoos can be more drying, they may not be suitable for those with dry or damaged hair unless followed by a rich conditioner. For a gentle volumizing option, try the Volumizing Shampoo from Native, which uses plant-based cleansers to add body without harsh sulfates.

• Best for: fine, thin, limp, or oily hair
• Key ingredients: rice protein, biotin, panthenol, lightweight polymers
• Avoid if: you have very dry, curly, or chemically treated hair

How to Determine Your Hair Type

Before choosing between moisturizing and volumizing shampoo, it's important to understand your hair type. The most common categories are straight, wavy, curly, and coily, but you should also consider your hair's porosity, thickness, and oiliness. A simple way to assess is to wash your hair with a gentle sulfate-free shampoo and observe how it behaves after air-drying.

If your hair feels dry, frizzy, or takes a long time to dry, you likely have low porosity hair that needs extra moisture. If it gets greasy quickly or feels flat by midday, you may have fine or oily hair that would benefit from a volumizing formula. For those with combination hair (oily roots and dry ends), consider using a volumizing shampoo on your scalp and a moisturizing conditioner on your ends.

• Fine hair: tends to get oily, lacks volume, looks flat quickly
• Dry hair: feels rough, prone to breakage, may have split ends
• Curly/coily hair: naturally drier, needs hydration to reduce frizz
• Oily hair: roots look greasy within 24 hours, may feel heavy

Moisturizing Shampoo vs Volumizing Shampoo: Side-by-Side Comparison

To make the decision easier, here's a quick comparison of the two shampoo types based on key factors. Keep in mind that individual results may vary depending on your hair's unique needs and the specific formula you choose.

Moisturizing shampoos excel at hydration and softness, while volumizing shampoos shine at adding lift and reducing oiliness. Neither is inherently better—the right choice depends entirely on your hair type and goals. For example, if you have fine hair that's also dry from coloring, you might alternate between both types throughout the week.

• Hydration: Moisturizing = high, Volumizing = low to moderate
• Volume boost: Moisturizing = low, Volumizing = high
• Best for dry hair: Moisturizing = yes, Volumizing = no
• Best for fine hair: Moisturizing = no (unless dry), Volumizing = yes
• Frizz control: Moisturizing = good, Volumizing = minimal
• Ideal wash frequency: Moisturizing = every 2-3 days, Volumizing = daily or every other day

When to Choose Moisturizing Shampoo

Moisturizing shampoo is your best bet if your hair feels dry, brittle, or lacks elasticity. It's also a great choice for those with curly or coily textures, as these hair types are prone to dryness due to the difficulty of natural oils traveling down the hair shaft. If you live in a dry climate or use heat styling tools frequently, a moisturizing formula can help counteract damage.

For an effective yet gentle option, consider the Strengthening 2-in-1 Shampoo & Conditioner from Native, which combines moisturizing ingredients with strengthening proteins to support hair health. This type of product can simplify your routine while still delivering the hydration your hair craves. Just be sure to follow up with a lightweight conditioner if your hair tends to get greasy at the roots.

• You have dry, curly, or color-treated hair
• Your hair feels rough or tangles easily after washing
• You want to reduce frizz and improve softness

When to Choose Volumizing Shampoo

Volumizing shampoo is ideal if your hair falls flat quickly, lacks body, or gets oily within a day of washing. It works by lifting the hair cuticle slightly, which creates the appearance of thicker strands. This type of shampoo is also helpful for people with fine hair who want to achieve more texture and movement without using heavy styling products.

For a reliable volumizing option, try the Volumizing Shampoo from Native, which is formulated with clean ingredients that won't weigh your hair down. If you have a sensitive scalp, you can also pair it with a gentle scalp care product like the Scalp Detox Shampoo to remove buildup and promote a healthy environment for hair growth. Remember to focus the shampoo on your roots and scalp, and use conditioner only on your mid-lengths and ends.

• You have fine, thin, or limp hair
• Your hair gets greasy quickly at the roots
• You want more lift and body without extra products

Can You Use Both? Alternating Shampoos for Best Results

Many people find that alternating between a moisturizing and a volumizing shampoo gives them the best of both worlds. For example, you might use a volumizing shampoo on days when your hair feels flat or after a workout, and switch to a moisturizing shampoo once or twice a week to prevent dryness. This approach works especially well for those with combination hair types.

If you prefer an all-in-one solution, the Full & Thick 2-in-1 Shampoo & Conditioner offers a balanced formula that provides both volume and moisture in one step. It's designed for fine to medium hair that needs a little extra body without sacrificing softness. Experiment with your routine to find the perfect rhythm for your hair's changing needs throughout the seasons.

• Use volumizing shampoo 2-3 times per week for lift
• Use moisturizing shampoo 1-2 times per week for hydration
• Always condition mid-lengths and ends, even with volumizing shampoo

Finding the right shampoo doesn't have to be complicated. By understanding your hair type and the specific benefits of moisturizing versus volumizing formulas, you can make an informed choice that leaves your hair looking and feeling its best. Whether you need extra hydration or a boost of volume, Native's clean, plant-based shampoos offer effective solutions for every hair type.
