Each person’s scalp type (dry, oily, sensitive)
and degree of hair damage is different. To avoid purchasing the wrong product,
we strongly recommend spending one minute completing our Hair Quiz.
The
system will analyze your actual condition and recommend the most accurate
shampoo and treatment combination tailored to you.

The key to effective hair care is personalization. Your hair may be fine
or coarse, straight or curly, and may require specific moisture or oil-control support.

Step 1 : Identify your primary scalp needs (oily, dry, or sensitive).

Step 2 : Identify your hair shaft needs (damaged, color-treated, dry, or
frizzy).

Recommendation: We strongly encourage taking our online Hair Quiz.
It analyzes your responses and provides a customized product plan designed
specifically for your unique needs, eliminating the uncertainty of guesswork.

Common scalp types include oily, dry, sensitive, and combination. You can identify your type by observing signs such as
oiliness, tightness, itchiness, or dandruff.

Hair texture is generally determined by strand thickness (fine or coarse), hair pattern (straight, curly, wavy), and condition
(healthy, dry, or damaged).

Oil-control and volumizing formulas are the most suitable. If your hair feels weighed down by buildup, pair them with a clarifying or deep-cleansing shampoo to reset the hair condition.

The key difference is the depth of action:

Conditioners work on the surface of the hair shaft, smoothing the cuticle, reducing tangles, and improving manageability — this is basic surface hydration.

Treatments penetrate deeper into the inner hair structure, replenishing amino acids, proteins, and oils, repairing damage, strengthening resilience, and reducing frizz — this is true restorative care.

Our products belong to the treatment category, containing cosmetic-grade repair ingredients that truly penetrate the hair, making them more than ordinary conditioners.

We recommend using our scalp care series, such as hair-strengthening shampoos and scalp treatments, which support a healthy scalp environment and strengthen hair roots.

If hair loss is severe, lifestyle adjustments and consultation with a dermatologist are also advised.

We recommend using Sage Purifying Shampoo to cleanse and balance scalp oil production, followed by Nutra Therapy Hair
Shampoo and Nutra Therapy Conditioner from mid-length to ends to
maintain moisture without weighing the hair down.

You may choose a moisturizing scalp shampoo such as Truffle Moisturizing Shampoo, which helps replenish moisture and maintain scalp comfort. Use warm water when washing, avoid over-cleansing, and
apply conditioners only to the ends.

• Dehydrated hair (needs moisture): Feels dry, rough, lacks elasticity, develops static easily, and breaks when pulled.

Care focus: Use products containing hyaluronic acid, aloe vera, glycerin, or
natural oils for hydration and softness.

• Protein-deficient hair (needs structural repair): Feels gummy or overly stretchy like a rubber band when wet, with severe split ends. Common after bleaching or perming.

Care focus: Use products with keratin, amino acids, or silk protein for rebuilding strength.

Best practice: Most damaged hair needs a balance of moisture and protein. Professional repair products are typically formulated with this optimal balance.

Many people assume that one shampoo can wash both the scalp and the hair.

This is a major misunderstanding!The scalp needs oil control and cleansing, while the hair strands need hydration and repair — their needs are different.

Using one product for both may cause:
• a scalp that becomes oilier
• dry, brittle ends
• increased frizz and breakage

Correct method: Treat shampooing as two steps — cleanse the scalp with an appropriate shampoo and treat the hair lengths with a hydrating or repairing shampoo.

Yes. Curly hair (including permed hair) is naturally drier and often more damaged, so it requires deeper hydration and repair. Straight hair, on the other hand, benefits more from lightweight, volumizing products. The Hair Quiz can help determine the best match.

Curly hair inherently dries out faster because of its structure. To enhance curl definition and bounce:

• Gentle cleansing: Use sulfate-free shampoos or consider co-washing to preserve natural oils.

• Reduce friction: Avoid rubbing with towels. Instead, use a cotton
T-shirt or microfiber towel to press water out gently.

• Moisture retention: Apply generous conditioner, cream, or oil to wet
hair to lock in moisture before drying.

• Low heat drying: When using a diffuser, choose low to medium heat and
airflow to avoid disrupting curl patterns or causing dryness.

Depending on the recipient, consider:

Premium gifts:
SH-RD Protein Cream, Gold Hair Mask, gift sets

Practical gifts:
Repair shampoo + conditioner sets, leave-in treatments

When unsure, choose our classic repair products or gift sets — they suit
most hair types and are always appreciated.

Choose products with broad compatibility. If the recipient cannot take the Hair Quiz, select items from our Classic Balancing
or All Hair Types series.

You may also invite them to complete the Hair Quiz and purchase according to
their results for a more personalized gift.

Select gentle, low-irritation products that suit most people:

Gentle shampoos:
free of harsh fragrances or SLS

Scalp care:
serums or scalp scrubs

Lightweight leave-in products: sprays or lightweight creams that won’t weigh
the hair down.

Avoid highly specialized or multi-step treatments that may not suit all users.

Hair product effectiveness is influenced by
seasonal changes, recent chemical treatments, and lifestyle factors. If the
results seem less effective, your scalp condition may have changed (for
example, becoming drier or oilier due to weather).

We recommend retaking the Hair
Quiz or contacting customer service for further guidance.

Use Nutra Therapy Conditioner, apply a Hair
Mask weekly, and apply SHRD Protein Cream as a leave-in treatment after washing. Consistent use improves smoothness and manageability over time.

You may begin using deep-repair treatments on the same day as your coloring or perm service. This helps stabilize and restore the hair structure more quickly.

Color-protecting products do work, though they are not magic —
they slow down the fading process, helping your hair maintain vibrancy and
brightness for a longer time.

Color-care formulas typically work by:

1. Adjusting shampoo pH to help close the cuticle.
2. Using gentler surfactants to reduce pigment loss
3. Adding moisture and repair ingredients for stronger hair
4. Sometimes including pigments (such as purple, blue, or pink shampoos) to maintain tone.
